+OMAP SSI controller bindings
+
+OMAP Synchronous Serial Interface (SSI) controller implements a legacy
+variant of MIPI's High Speed Synchronous Serial Interface (HSI).
+
+Required properties:
+- compatible:		Should include "ti,omap3-ssi".
+- reg-names:		Contains the values "sys" and "gdd" (in this order).
+- reg:			Contains a matching register specifier for each entry
+			in reg-names.
+- interrupt-names:	Contains the value "gdd_mpu".
+- interrupts: 		Contains matching interrupt information for each entry
+			in interrupt-names.
+- ranges:		Represents the bus address mapping between the main
+			controller node and the child nodes below.
+- clock-names:		Must include the following entries:
+  "ssi_ssr_fck": The OMAP clock of that name
+  "ssi_sst_fck": The OMAP clock of that name
+  "ssi_ick": The OMAP clock of that name
+- clocks:		Contains a matching clock specifier for each entry in
+			clock-names.
+- #address-cells:	Should be set to <1>
+- #size-cells:		Should be set to <1>
+
+Each port is represented as a sub-node of the ti,omap3-ssi device.
+
+Required Port sub-node properties:
+- compatible:		Should be set to the following value
+			ti,omap3-ssi-port (applicable to OMAP34xx devices)
+- reg-names:		Contains the values "tx" and "rx" (in this order).
+- reg:			Contains a matching register specifier for each entry
+			in reg-names.
+- interrupt-parent	Should be a phandle for the interrupt controller
+- interrupts:		Should contain interrupt specifiers for mpu interrupts
+			0 and 1 (in this order).
+- ti,ssi-cawake-gpio:	Defines which GPIO pin is used to signify CAWAKE
+			events for the port. This is an optional board-specific
+			property. If it's missing the port will not be
+			enabled.
+
+Example for Nokia N900:
+

@@ -73,6 +73,65 @@ The IRQ portions of the GPIO block are implemented using an irqchip, using
 the header <linux/irq.h>. So basically such a driver is utilizing two sub-
 systems simultaneously: gpio and irq.
 
+GPIO irqchips usually fall in one of two categories:
+
+* CHAINED GPIO irqchips: these are usually the type that is embedded on
+  an SoC. This means that there is a fast IRQ handler for the GPIOs that
+  gets called in a chain from the parent IRQ handler, most typically the
+  system interrupt controller. This means the GPIO irqchip is registered
+  using irq_set_chained_handler() or the corresponding
+  gpiochip_set_chained_irqchip() helper function, and the GPIO irqchip
+  handler will be called immediately from the parent irqchip, while
+  holding the IRQs disabled. The GPIO irqchip will then end up calling
+  something like this sequence in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      chained_irq_enter(...);
+      generic_handle_irq(...);
+      chained_irq_exit(...);
+
+  Chained GPIO irqchips typically can NOT set the .can_sleep flag on
+  struct gpio_chip, as everything happens directly in the callbacks.
+
+* NESTED THREADED GPIO irqchips: these are off-chip GPIO expanders and any
+  other GPIO irqchip residing on the other side of a sleeping bus. Of course
+  such drivers that need slow bus traffic to read out IRQ status and similar,
+  traffic which may in turn incur other IRQs to happen, cannot be handled
+  in a quick IRQ handler with IRQs disabled. Instead they need to spawn a
+  thread and then mask the parent IRQ line until the interrupt is handled
+  by the driver. The hallmark of this driver is to call something like
+  this in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      ...
+      handle_nested_irq(irq);
+
+  The hallmark of threaded GPIO irqchips is that they set the .can_sleep
+  flag on struct gpio_chip to true, indicating that this chip may sleep
+  when accessing the GPIOs.
+
+To help out in handling the set-up and management of GPIO irqchips and the
+associated irqdomain and resource allocation callbacks, the gpiolib has
+some helpers that can be enabled by selecting the GPIOLIB_IRQCHIP Kconfig
+symbol:
+
+* gpiochip_irqchip_add(): adds an irqchip to a gpiochip. It will pass
+  the struct gpio_chip* for the chip to all IRQ callbacks, so the callbacks
+  need to embed the gpio_chip in its state container and obtain a pointer
+  to the container using container_of().
+  (See Documentation/driver-model/design-patterns.txt)
+
+* gpiochip_set_chained_irqchip(): sets up a chained irq handler for a
+  gpio_chip from a parent IRQ and passes the struct gpio_chip* as handler
+  data. (Notice handler data, since the irqchip data is likely used by the
+  parent irqchip!) This is for the chained type of chip.
+
+To use the helpers please keep the following in mind:
+
+- Make sure to assign all relevant members of the struct gpio_chip so that
+  the irqchip can initialize. E.g. .dev and .can_sleep shall be set up
+  properly.
+
 It is legal for any IRQ consumer to request an IRQ from any irqchip no matter
 if that is a combined GPIO+IRQ driver. The basic premise is that gpio_chip and
 irq_chip are orthogonal, and offering their services independent of each

+HSI - High-speed Synchronous Serial Interface
+
+1. Introduction
+~~~~~~~~~~~~~~~
+
+High Speed Syncronous Interface (HSI) is a fullduplex, low latency protocol,
+that is optimized for die-level interconnect between an Application Processor
+and a Baseband chipset. It has been specified by the MIPI alliance in 2003 and
+implemented by multiple vendors since then.
+
+The HSI interface supports full duplex communication over multiple channels
+(typically 8) and is capable of reaching speeds up to 200 Mbit/s.
+
+The serial protocol uses two signals, DATA and FLAG as combined data and clock
+signals and an additional READY signal for flow control. An additional WAKE
+signal can be used to wakeup the chips from standby modes. The signals are
+commonly prefixed by AC for signals going from the application die to the
+cellular die and CA for signals going the other way around.
+

+2. HSI Subsystem in Linux
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the Linux kernel the hsi subsystem is supposed to be used for HSI devices.
+The hsi subsystem contains drivers for hsi controllers including support for
+multi-port controllers and provides a generic API for using the HSI ports.
+
+It also contains HSI client drivers, which make use of the generic API to
+implement a protocol used on the HSI interface. These client drivers can
+use an arbitrary number of channels.
+
+3. hsi-char Device
+~~~~~~~~~~~~~~~~~~
+
+Each port automatically registers a generic client driver called hsi_char,
+which provides a charecter device for userspace representing the HSI port.
+It can be used to communicate via HSI from userspace. Userspace may
+configure the hsi_char device using the following ioctl commands:
+
+* HSC_RESET:
+ - flush the HSI port
+
+* HSC_SET_PM
+ - enable or disable the client.
+
+* HSC_SEND_BREAK
+ - send break
+
+* HSC_SET_RX
+ - set RX configuration
+
+* HSC_GET_RX
+ - get RX configuration
+
+* HSC_SET_TX

-NOTE:  This driver is obsolete.  Digi provides a 2.6 driver (dgdm) at
-http://www.digi.com for PCI cards.  They no longer maintain this driver,
-and have no 2.6 driver for ISA cards.
-
-This driver requires a number of user-space tools.  They can be acquired from
-http://www.digi.com, but only works with 2.4 kernels.
-
-
-The Digi Intl. epca driver. 
-----------------------------
-The Digi Intl. epca driver for Linux supports the following boards:
-
-Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve 
-Digi EISA/Xem, PCI/Xem, PCI/Xr 
-
-Limitations:
-------------
-Currently the driver only autoprobes for supported PCI boards. 
-
-The Linux MAKEDEV command does not support generating the Digiboard
-Devices.  Users executing digiConfig to setup EISA and PC series cards
-will have their device nodes automatically constructed (cud?? for ~CLOCAL,
-and ttyD?? for CLOCAL).  Users wishing to boot their board from the LILO
-prompt, or those users booting PCI cards may use buildDIGI to construct 
-the necessary nodes. 
-
-Notes:
-------
-This driver may be configured via LILO.  For users who have already configured
-their driver using digiConfig, configuring from LILO will override previous 
-settings.  Multiple boards may be configured by issuing multiple LILO command 
-lines.  For examples see the bottom of this document.
-
-Device names start at 0 and continue up.  Beware of this as previous Digi 
-drivers started device names with 1.
-
-PCI boards are auto-detected and configured by the driver.  PCI boards will
-be allocated device numbers (internally) beginning with the lowest PCI slot
-first.  In other words a PCI card in slot 3 will always have higher device
-nodes than a PCI card in slot 1. 
-
-LILO config examples:
----------------------
-Using LILO's APPEND command, a string of comma separated identifiers or 
-integers can be used to configure supported boards.  The six values in order 
-are:
-
-   Enable/Disable this card or Override,
-   Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2), 
-                 EISA/Xem (3), PC/64Xe (4), PC/Xi (5), 
-   Enable/Disable alternate pin arrangement,
-   Number of ports on this card,
-   I/O Port where card is configured (in HEX if using string identifiers),
-   Base of memory window (in HEX if using string identifiers), 
-
-NOTE : PCI boards are auto-detected and configured.  Do not attempt to 
-configure PCI boards with the LILO append command.  If you wish to override
-previous configuration data (As set by digiConfig), but you do not wish to
-configure any specific card (Example if there are PCI cards in the system) 
-the following override command will accomplish this:
--> append="digi=2"
-
-Samples:
-   append="digiepca=E,PC/Xe,D,16,200,D0000"
-                  or
-   append="digi=1,0,0,16,512,851968"
-
-Supporting Tools:
------------------
-Supporting tools include digiDload, digiConfig, buildPCI, and ditty.  See
-drivers/char/README.epca for more details.  Note,
-this driver REQUIRES that digiDload be executed prior to it being used. 
-Failure to do this will result in an ENODEV error.

-Misc. notes for RISCom/8 serial driver, in no particular order :)
-
-1) This driver can support up to 4 boards at time.
-   Use string "riscom8=0xXXX,0xXXX,0xXXX,0xXXX" at LILO prompt, for
-   setting I/O base addresses for boards. If you compile driver
-   as module use modprobe options "iobase=0xXXX iobase1=0xXXX iobase2=..."
-
-2) The driver partially supports famous 'setserial' program, you can use almost
-   any of its options, excluding port & irq settings.
-
-3) There are some misc. defines at the beginning of riscom8.c, please read the 
-   comments and try to change some of them in case of problems.
-
-4) I consider the current state of the driver as BETA.
-
-5) SDL Communications WWW page is http://www.sdlcomm.com.
-
-6) You can use the MAKEDEV program to create RISCom/8 /dev/ttyL* entries.
-
-7) Minor numbers for first board are 0-7, for second 8-15, etc.

-Intro
-=====
-
- 
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources?  And the manual of one of the boards in your computer?
-
-
-Addresses and interrupts
-========================
-
-Address dip switch settings:
-The dip switch sets bits 2-9 of the IO address.

-   0 | X   X X X X X X |

-
-Base address 0x100 caused a conflict in one of my computers once.  I
-haven't the foggiest why. My Specialix card is now at 0x180.  My
-other computer runs just fine with the Specialix card at 0x100....
-The card occupies 4 addresses, but actually only two are really used.
-
-The PCI version doesn't have any dip switches. The BIOS assigns
-an IO address. 
-
-The driver now still autoprobes at 0x100, 0x180, 0x250 and 0x260.  If
-that causes trouble for you, please report that. I'll remove
-autoprobing then.
-
-The driver will tell the card what IRQ to use, so you don't have to
-change any jumpers to change the IRQ. Just use a command line
-argument (irq=xx) to the insmod program to set the interrupt.
-
-The BIOS assigns the IRQ on the PCI version. You have no say in what
-IRQ to use in that case. 
-
-If your specialix cards are not at the default locations, you can use
-the kernel command line argument "specialix=io0,irq0,io1,irq1...".
-Here "io0" is the io address for the first card, and "irq0" is the
-irq line that the first card should use. And so on. 
-
-Examples. 
-
-You use the driver as a module and have three cards at 0x100, 0x250
-and 0x180. And some way or another you want them detected in that
-order. Moreover irq 12 is taken (e.g. by your PS/2 mouse).
-
-  insmod specialix.o iobase=0x100,0x250,0x180 irq=9,11,15
-
-The same three cards, but now in the kernel would require you to
-add 
-
-   specialix=0x100,9,0x250,11,0x180,15
-
-to the command line. This would become 
-
-   append="specialix=0x100,9,0x250,11,0x180,15" 
-
-in your /etc/lilo.conf file if you use lilo. 
-
-The Specialix driver is slightly odd: It allows you to have the second
-or third card detected without having a first card. This has
-advantages and disadvantages. A slot that isn't filled by an ISA card,
-might be filled if a PCI card is detected. Thus if you have an ISA
-card at 0x250 and a PCI card, you would get:
-
-sx0: specialix IO8+ Board at 0x100 not found.
-sx1: specialix IO8+ Board at 0x180 not found.
-sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev. B.
-sx3: specialix IO8+ Board at 0x260 not found.
-sx0: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-This would happen if you don't give any probe hints to the driver. 
-If you would specify:
-
-   specialix=0x250,11
-
-you'd get the following messages:
-
-sx0: specialix IO8+ board detected at 0x250, IRQ 11, CD1865 Rev. B.
-sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-ISA probing is aborted after the IO address you gave is exhausted, and
-the PCI card is now detected as the second card. The ISA card is now
-also forced to IRQ11....
-
-
-Baud rates
-==========
-
-The rev 1.2 and below boards use a CL-CD1864. These chips can only 
-do 64kbit. The rev 1.3 and newer boards use a CL-CD1865. These chips
-are officially capable of 115k2.
-
-The Specialix card uses a 25MHz crystal (in times two mode, which in
-fact is a divided by two mode). This is not enough to reach the rated
-115k2 on all ports at the same time. With this clock rate you can only
-do 37% of this rate. This means that at 115k2 on all ports you are
-going to lose characters (The chip cannot handle that many incoming
-bits at this clock rate.) (Yes, you read that correctly: there is a
-limit to the number of -=bits=- per second that the chip can handle.)
-
-If you near the "limit" you will first start to see a graceful
-degradation in that the chip cannot keep the transmitter busy at all
-times. However with a central clock this slow, you can also get it to
-miss incoming characters. The driver will print a warning message when
-you are outside the official specs. The messages usually show up in
-the file /var/log/messages .
-
-The specialix card cannot reliably do 115k2. If you use it, you have
-to do "extensive testing" (*) to verify if it actually works.
-
-When "mgetty" communicates with my modem at 115k2 it reports:
-got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a]
-                            ^^^^ ^^^^    ^^^^ 
-
-The three characters that have the "^^^" under them have suffered a
-bit error in the highest bit. In conclusion: I've tested it, and found
-that it simply DOESN'T work for me. I also suspect that this is also
-caused by the baud rate being just a little bit out of tune. 
-
-I upgraded the crystal to 66Mhz on one of my Specialix cards. Works
-great! Contact me for details. (Voids warranty, requires a steady hand
-and more such restrictions....)

-Hardware handshaking issues.
-============================
-
-The driver can be told to operate in two different ways. The default
-behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when
-hardware handshaking is off. It behaves as the RTS hardware
-handshaking signal when hardware handshaking is selected.
-
-When you use this, you have to use the appropriate cable. The
-cable will either be compatible with hardware handshaking or with
-software handshaking. So switching on the fly is not really an
-option.
-
-I actually prefer to use the "specialix.sx_rtscts=1" option.
-This makes the DTR/RTS pin always an RTS pin, and ioctls to
-change DTR are always ignored. I have a cable that is configured
-for this. 
-
-
-Ports and devices
-=================
-
-Port 0 is the one furthest from the card-edge connector.
-
-Devices:
-
-You should make the devices as follows:
-
-bash
-cd /dev
-for i in  0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 \
-         16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
-do
-  echo -n "$i "
-  mknod /dev/ttyW$i c 75 $i
-  mknod /dev/cuw$i c 76 $i
-done
-echo ""
-
-If your system doesn't come with these devices preinstalled, bug your
-linux-vendor about this. They have had ample time to get this
-implemented by now.
-
-You cannot have more than 4 boards in one computer. The card only
-supports 4 different interrupts. If you really want this, contact me
-about this and I'll give you a few tips (requires soldering iron)....
-
-If you have enough PCI slots, you can probably use more than 4 PCI
-versions of the card though.... 
-
-The PCI version of the card cannot adhere to the mechanical part of
-the PCI spec because the 8 serial connectors are simply too large. If
-it doesn't fit in your computer, bring back the card.
-
-
-------------------------------------------------------------------------
-
-
-  Fixed bugs and restrictions:
-       - During initialization, interrupts are blindly turned on.
-            Having a shadow variable would cause an extra memory
-            access on every IO instruction. 
-       - The interrupt (on the card) should be disabled when we
-         don't allocate the Linux end of the interrupt. This allows 
-         a different driver/card to use it while all ports are not in
-         use..... (a la standard serial port)
-       == An extra _off variant of the sx_in and sx_out macros are
-          now available. They don't set the interrupt enable bit.
-          These are used during initialization. Normal operation uses
-          the old variant which enables the interrupt line.
-       - RTS/DTR issue needs to be implemented according to 
-         specialix' spec.
-            I kind of like the "determinism" of the current 
-            implementation. Compile time flag?
-       == Ok. Compile time flag! Default is how Specialix likes it.
-       == Now a config time flag! Gets saved in your config file. Neat!
-       - Can you set the IO address from the lilo command line?
-            If you need this, bug me about it, I'll make it. 
-       == Hah! No bugging needed. Fixed! :-)
-       - Cirrus logic hasn't gotten back to me yet why the CD1865 can
-            and the CD1864 can't do 115k2. I suspect that this is
-            because the CD1864 is not rated for 33MHz operation.
-            Therefore the CD1864 versions of the card can't do 115k2 on 
-            all ports just like the CD1865 versions. The driver does
-            not block 115k2 on CD1864 cards. 
-        == I called the Cirrus Logic representative here in Holland.
-           The CD1864 databook is identical to the CD1865 databook, 
-           except for an extra warning at the end. Similar Bit errors
-           have been observed in testing at 115k2 on both an 1865 and
-           a 1864 chip. I see no reason why I would prohibit 115k2 on
-           1864 chips and not do it on 1865 chips. Actually there is
-           reason to prohibit it on BOTH chips. I print a warning.
-           If you use 115k2, you're on your own. 
-       - A spiky CD may send spurious HUPs. Also in CLOCAL???
-         -- A fix for this turned out to be counter productive. 
-            Different fix? Current behaviour is acceptable?
-         -- Maybe the current implementation is correct. If anybody
-            gets bitten by this, please report, and it will get fixed.
-
-         -- Testing revealed that when in CLOCAL, the problem doesn't
-            occur. As warned for in the CD1865 manual, the chip may
-            send modem intr's on a spike. We could filter those out,
-            but that would be a cludge anyway (You'd still risk getting
-            a spurious HUP when two spikes occur.).....
- 
-
-
-  Bugs & restrictions:
-       - This is a difficult card to autoprobe.
-            You have to WRITE to the address register to even 
-            read-probe a CD186x register. Disable autodetection?
-         -- Specialix: any suggestions?

-Introduction
-============
-
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources?  And the manual of one of the boards in your computer?
-
-
-Theory of operation
-===================
-
-An important thing to know is that the driver itself doesn't have the
-firmware for the card. This means that you need the separate package
-"sx_firmware". For now you can get the source at
-
-	ftp://ftp.bitwizard.nl/specialix/sx_firmware_<version>.tgz
-
-The firmware load needs a "misc" device, so you'll need to enable the
-"Support for user misc device modules" in your kernel configuration.
-The misc device needs to be called "/dev/specialix_sxctl". It needs
-misc major 10, and minor number 167 (assigned by HPA). The section
-on creating device files below also creates this device. 
-
-After loading the sx.o module into your kernel, the driver will report
-the number of cards detected, but because it doesn't have any
-firmware, it will not be able to determine the number of ports. Only
-when you then run "sx_firmware" will the firmware be downloaded and
-the rest of the driver initialized. At that time the sx_firmware
-program will report the number of ports installed.
-
-In contrast with many other multi port serial cards, some of the data
-structures are only allocated when the card knows the number of ports
-that are connected. This means we won't waste memory for 120 port
-descriptor structures when you only have 8 ports. If you experience
-problems due to this, please report them: I haven't seen any.
-
-
-Interrupts
-==========
-
-A multi port serial card, would generate a horrendous amount of
-interrupts if it would interrupt the CPU for every received
-character. Even more than 10 years ago, the trick not to use
-interrupts but to poll the serial cards was invented.
-
-The SX card allow us to do this two ways. First the card limits its
-own interrupt rate to a rate that won't overwhelm the CPU. Secondly,
-we could forget about the cards interrupt completely and use the
-internal timer for this purpose.
-
-Polling the card can take up to a few percent of your CPU. Using the
-interrupts would be better if you have most of the ports idle. Using
-timer-based polling is better if your card almost always has work to
-do. You save the separate interrupt in that case.
-
-In any case, it doesn't really matter all that much. 
-
-The most common problem with interrupts is that for ISA cards in a PCI
-system the BIOS has to be told to configure that interrupt as "legacy
-ISA". Otherwise the card can pull on the interrupt line all it wants
-but the CPU won't see this.
-
-If you can't get the interrupt to work, remember that polling mode is
-more efficient (provided you actually use the card intensively).
-
-
-Allowed Configurations
-======================
-
-Some configurations are disallowed. Even though at a glance they might
-seem to work, they are known to lockup the bus between the host card
-and the device concentrators. You should respect the drivers decision
-not to support certain configurations. It's there for a reason.
-
-Warning: Seriously technical stuff ahead. Executive summary: Don't use
-SX cards except configured at a 64k boundary. Skip the next paragraph.
-
-The SX cards can theoretically be placed at a 32k boundary. So for
-instance you can put an SX card at 0xc8000-0xd7fff. This is not a
-"recommended configuration". ISA cards have to tell the bus controller
-how they like their timing. Due to timing issues they have to do this
-based on which 64k window the address falls into. This means that the
-32k window below and above the SX card have to use exactly the same
-timing as the SX card. That reportedly works for other SX cards. But
-you're still left with two useless 32k windows that should not be used
-by anybody else.
-
-
-Configuring the driver
-======================
-
-PCI cards are always detected. The driver auto-probes for ISA cards at
-some sensible addresses. Please report if the auto-probe causes trouble
-in your system, or when a card isn't detected.
-
-I'm afraid I haven't implemented "kernel command line parameters" yet.
-This means that if the default doesn't work for you, you shouldn't use
-the compiled-into-the-kernel version of the driver. Use a module
-instead.  If you convince me that you need this, I'll make it for
-you. Deal?
-
-I'm afraid that the module parameters are a bit clumsy. If you have a
-better idea, please tell me.
-
-You can specify several parameters:
-
-	sx_poll: number of jiffies between timer-based polls.
-
-		Set this to "0" to disable timer based polls. 
-                Initialization of cards without a working interrupt
-                will fail.
-
-		Set this to "1" if you want a polling driver. 
-		(on Intel: 100 polls per second). If you don't use
-                fast baud rates, you might consider a value like "5". 
-                (If you don't know how to do the math, use 1).
-
-	sx_slowpoll: Number of jiffies between timer-based polls. 
- 		Set this to "100" to poll once a second. 
-		This should get the card out of a stall if the driver
-                ever misses an interrupt. I've never seen this happen,
-                and if it does, that's a bug. Tell me. 
-
-	sx_maxints: Number of interrupts to request from the card. 
-		The card normally limits interrupts to about 100 per
-		second to offload the host CPU. You can increase this
-		number to reduce latency on the card a little.
-		Note that if you give a very high number you can overload
-		your CPU as well as the CPU on the host card. This setting 
-		is inaccurate and not recommended for SI cards (But it 
-		works). 
-
-	sx_irqmask: The mask of allowable IRQs to use. I suggest you set 
-		this to 0 (disable IRQs all together) and use polling if 
-		the assignment of IRQs becomes problematic. This is defined
-		as the sum of (1 << irq) 's that you want to allow. So 
-		sx_irqmask of 8 (1 << 3) specifies that only irq 3 may
-		be used by the SX driver. If you want to specify to the 
-		driver: "Either irq 11 or 12 is ok for you to use", then
-		specify (1 << 11) | (1 << 12) = 0x1800 . 
-
-	sx_debug: You can enable different sorts of debug traces with this. 
-		At "-1" all debugging traces are active. You'll get several
-		times more debugging output than you'll get characters 
-		transmitted. 
-
-
-Baud rates
-==========
-
-Theoretically new SXDCs should be capable of more than 460k
-baud. However the line drivers usually give up before that.  Also the
-CPU on the card may not be able to handle 8 channels going at full
-blast at that speed. Moreover, the buffers are not large enough to
-allow operation with 100 interrupts per second. You'll have to realize
-that the card has a 256 byte buffer, so you'll have to increase the
-number of interrupts per second if you have more than 256*100 bytes
-per second to transmit.  If you do any performance testing in this
-area, I'd be glad to hear from you...
-
-(Psst Linux users..... I think the Linux driver is more efficient than
-the driver for other OSes. If you can and want to benchmark them
-against each other, be my guest, and report your findings...... :-)
-
-
-Ports and devices
-=================
-
-Port 0 is the top connector on the module closest to the host
-card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8
-instead of from 0 to 7, as they are numbered by linux. I'm stubborn in
-this: I know for sure that I wouldn't be able to calculate which port
-is which anymore if I would change that....
-
-
-Devices:
-
-You should make the device files as follows:
-
-#!/bin/sh
-# (I recommend that you cut-and-paste this into a file and run that)
-cd /dev
-t=0
-mknod specialix_sxctl c 10 167
-while [ $t -lt 64 ]
-  do 
-  echo -n "$t "
-  mknod ttyX$t c 32 $t
-  mknod cux$t  c 33 $t
-  t=`expr $t + 1`
-done
-echo ""
-rm /etc/psdevtab
-ps > /dev/null
-
-
-This creates 64 devices. If you have more, increase the constant on
-the line with "while". The devices start at 0, as is customary on
-Linux. Specialix seems to like starting the numbering at 1. 
-
-If your system doesn't come with these devices pre-installed, bug your
-linux-vendor about this. They should have these devices
-"pre-installed" before the new millennium. The "ps" stuff at the end
-is to "tell" ps that the new devices exist.
-
-Officially the maximum number of cards per computer is 4. This driver
-however supports as many cards in one machine as you want. You'll run
-out of interrupts after a few, but you can switch to polled operation
-then. At about 256 ports (More than 8 cards), we run out of minor
-device numbers. Sorry. I suggest you buy a second computer.... (Or
-switch to RIO).

+
+在�些平�上，所谓的内存映射I/O是弱顺�。在这些平�上，驱动开�者有责任
+��I/O内存映射地�的写�作按程�图�的顺�达到设备。通常读�一个“安全�
+设备寄存器或桥寄存器，触�IO芯片清刷未处�的写�作到达设备��处�读�作，
+而达到��目的。驱动程�通常在spinlock�护的临界区退出之�使用这�技术。
+这也�以����的写�作�在��的写�作之�到达设备（这�常类似于内存
+�障�作，mb()，�过仅适用于I/O）。
+
+�设一个设备驱动程的具体例�：
+
+        ...
+CPU A:  spin_lock_irqsave(&dev_lock, flags)
+CPU A:  val = readl(my_status);
+CPU A:  ...
+CPU A:  writel(newval, ring_ptr);
+CPU A:  spin_unlock_irqrestore(&dev_lock, flags)
+        ...
+CPU B:  spin_lock_irqsave(&dev_lock, flags)
+CPU B:  val = readl(my_status);
+CPU B:  ...
+CPU B:  writel(newval2, ring_ptr);
+CPU B:  spin_unlock_irqrestore(&dev_lock, flags)
+        ...
+
+上述例�中，设备�能会先接收到newval2的值，然�接收到newval的值，问题就
+�生了。�过很容易通过下�方法�修�：
+
+        ...
+CPU A:  spin_lock_irqsave(&dev_lock, flags)
+CPU A:  val = readl(my_status);
+CPU A:  ...
+CPU A:  writel(newval, ring_ptr);
+CPU A:  (void)readl(safe_register); /* �置寄存器？*/

+ * function with or 0 if no stack switching is requested, a2-a7 -- the
+ * function call's first six arguments, and the stack -- the remaining
+ * arguments (up to O32_ARGC, including a2-a7).  Static registers, gp
+ * and fp are preserved, v0 holds the result.  This code relies on the
+ * called o32 function for sp and ra restoration and this dispatcher has
+ * to be placed in a KSEGx (or KUSEG) address space.  Any pointers
+ * passed have to point to addresses within one of these spaces as well.

+/**
+ * DOC: output probing helper overview
+ *
+ * This library provides some helper code for output probing. It provides an
+ * implementation of the core connector->fill_modes interface with
+ * drm_helper_probe_single_connector_modes.
+ *
+ * It also provides support for polling connectors with a work item and for
+ * generic hotplug interrupt handling where the driver doesn't or cannot keep
+ * track of a per-connector hpd interrupt.
+ *
+ * This helper library can be used independently of the modeset helper library.
+ * Drivers can also overwrite different parts e.g. use their own hotplug
+ * handling code to avoid probing unrelated outputs.

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames.  With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.

-	---help---
-	  The frame buffer device provides an abstraction for the graphics
-	  hardware. It represents the frame buffer of some video hardware and
-	  allows application software to access the graphics hardware through
-	  a well-defined interface, so the software doesn't need to know
-	  anything about the low-level (hardware register) stuff.
-
-	  Frame buffer devices work identically across the different
-	  architectures supported by Linux and make the implementation of
-	  application programs easier and more portable; at this point, an X
-	  server exists which uses the frame buffer device exclusively.
-	  On several non-X86 architectures, the frame buffer device is the
-	  only way to use the graphics hardware.
-
-	  The device is accessed through special device nodes, usually located
-	  in the /dev directory, i.e. /dev/fb*.
-
-	  You need an utility program called fbset to make full use of frame
-	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-	  and the Framebuffer-HOWTO at
-	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
-	  information.
-
-	  Say Y here and to the driver for your graphics board below if you
-	  are compiling a kernel for a non-x86 architecture.
-
-	  If you are compiling for the x86 architecture, you can say Y if you
-	  want to play with it, but it is not essential. Please note that
-	  running graphical applications that directly touch the hardware
-	  (e.g. an accelerated X server) and that are not frame buffer
-	  device-aware may cause unexpected results. If unsure, say N.

+menuconfig FB
+	tristate "Support for frame buffer devices"
+	---help---
+	  The frame buffer device provides an abstraction for the graphics
+	  hardware. It represents the frame buffer of some video hardware and
+	  allows application software to access the graphics hardware through
+	  a well-defined interface, so the software doesn't need to know
+	  anything about the low-level (hardware register) stuff.
+
+	  Frame buffer devices work identically across the different
+	  architectures supported by Linux and make the implementation of
+	  application programs easier and more portable; at this point, an X
+	  server exists which uses the frame buffer device exclusively.
+	  On several non-X86 architectures, the frame buffer device is the
+	  only way to use the graphics hardware.
+
+	  The device is accessed through special device nodes, usually located
+	  in the /dev directory, i.e. /dev/fb*.
+
+	  You need an utility program called fbset to make full use of frame
+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
+	  and the Framebuffer-HOWTO at
+	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
+	  information.
+
+	  Say Y here and to the driver for your graphics board below if you
+	  are compiling a kernel for a non-x86 architecture.
+
+	  If you are compiling for the x86 architecture, you can say Y if you
+	  want to play with it, but it is not essential. Please note that
+	  running graphical applications that directly touch the hardware
+	  (e.g. an accelerated X server) and that are not frame buffer
+	  device-aware may cause unexpected results. If unsure, say N.

+	 transfers do not work for your driver and if you are using
+	 nvidiafb, i810fb or savagefb.
+
+	 In general, choosing Y for this option is safe.  If you
+	 experience extremely long delays while booting before you get

+         This enables tile blitting.  Tile blitting is a drawing technique
+	 where the screen is divided into rectangular sections (tiles), whereas
+	 the standard blitting divides the screen into pixels. Because the
+	 default drawing element is a tile, drawing functions will be passed
+	 parameters in terms of number of tiles instead of number of pixels.
+	 For example, to draw a single character, instead of using bitmaps,
+	 an index to an array of bitmaps will be used.  To clear or move a
+	 rectangular section of a screen, the rectangle will be described in
+	 terms of number of tiles in the x- and y-axis.
+
+	 This is particularly important to one driver, matroxfb.  If
+	 unsure, say N.
