Fix PCIe clock and reset not conforming to specification by moving PCIe
reset handling including the PLX PEX 8605 errata 5 workaround from the
board platform data into the right places timing wise in the PCIe driver
itself.
Also add a kernel command line argument to allow using the Apalis GPIO7
as a regular GPIO rather than for above mentioned PLX PEX 8605
workaround:
pex_perst=0

The Ixora carrier board has a few MXM3 pins repurposed as follows:
Functionality MXM3 Pin
LED4_RED 146
LED4_GREEN 162
LED5_RED 156
LED5_GREEN 152
PCIE1_WDISABLE_N 144
SW3 160
UART2_3_RS232_FOFF_N 164
This patch allows uncommenting an IXORA define in the board header file
in order to make use of those repurposed pins.
Please note that those pins are usually used for the 8-bit MMC/SD slot
aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes
the output driver behaviour in a way preventing any regular GPIO use.
This patch therefore explicitly does not register the SDHCI driver on
this controller instance in the Ixora case to avoid this.

Add a comment about DAP FS pin mux requiring INPUT when operating as I2S slave.
Add a comment about DAP SCLK requiring INPUT even when operating as I2S master.
Add a comment about is_i2s_master in the platform data meaning T30 SoC is I2S

This patch adds optional UHS support for the 8-bit MMC controller.
Please note that this requires V1.1A or later module hardware plus the
pull-up resistors on the data as well as the command signal lines of
your carrier board need to be removed (e.g. R46 to R54 on our Apalis
Evaluation Board V1.1A). If those pre-requisites are met support can be
enabled using the following kernel command line parameter:
mmc_uhs=1
|
|
Certain low-speed USB devices were not detected correctly when plugged
into a running system.
|

Both the Apalis EvalBoard as well as Ixora allow their LTC2954
pushbutton on/off controller to optionally initiate orderly shutdown
via GPIO interrupt on GPIO5 upon short power button press (short here
meaning really short unless C137 resp. C35 is assembled). For this to
work the following wiring is required:
Apalis EvalBoard V1.1a X61-4 to X2-6
Ixora V1.0a X5-4 to X27-17
For systemd/logind to actually use this as a power-switch a custom udev
rule /etc/udev/rules.d/70-power-switch-apalis_t30.rules as follows is
required:
# Specific rule for apalis_t30:
#
# Apalis T30's power button is not part of the kernel acpi subsystem.
# Let's manually add the power-switch tag to control its behaviour with
# systemd/logind
ACTION=="remove", GOTO="power_apalis_t30_end"
SUBSYSTEM=="input", KERNEL=="event1", TAG+="power-switch"
LABEL="power_apalis_t30_end"

Both the Apalis EvalBoard as well as Ixora allow their LTC2954
pushbutton on/off controller to optionally be forced off by using a
GPIO. This patch implements this upon poweroff/shutdown using Apalis
GPIO6 which happens to be internally pulled-up upon power-on reset
(otherwise we would immediately get powered off again). For this to
work the following wiring is required:
Apalis EvalBoard V1.1a X2-A5 to X61-5
Ixora V1.0a X27-18 to X5-5

The wake-up-key (formerly power-key) on MXM3 pin 37 aka WAKE1_MICO is
actually active-low due to the EvalBoard v1.1a having 4.7 K pull-up.
This patch fixes this.
While at it also get rid of the custom wakeup_key handling blindly
copied from T20 as non of the other T30 boards do this and it anyway
might only be required for LP0 which we anyway do not support so far.

This patch fixes a clock related audio hub driver lock-up observed when
booting with mainline U-Boot which we are in the process of migrating
to now.

Use HDA HDMI audio now on Colibri T30 as well allowing for up to 7.1
multi-channel playback. Split board sound initialisation between Apalis
and Colibri T30 in order to distinguish better between default SPDIF
being supported out-of-the-box on Apalis vs. this being an optional
feature for the Colibri. Therefore remove SPDIF for the Colibri T30.
While at it add csus clock required for vi_sensor camera master clock
on Apalis T30 and clk_out_2/extern2 for Colibri T30, fix debug UART1
initialisation, get rid of spurious CONFIG_SND_USB enable and further
clean-up both board platform data files.
|
|
Fix (Colibri) resp. introduce (Apalis) SPI device controller data to
properly use HW based chip select with one clock of setup and hold time
each for both MCP2515 CAN controller(s) as well as spidev.
|
|
The 1.8V quirk also affected the internal eMMC which disabled newer
modes such as SDR50, SDR104 and DDR50. This in turn lead to an
out of spec usage since the clock was still 50MHz.
By creating a no_1v8 field in the platform data we can now enable
this work around on a per-instance basis. Hence we enable the
quirk only on the controllers which are connected to the external
SD-slots.

This commit adds settings such as:
- values of horizontal/vertical active start,
- enabling/disabling internal sync,
to the private data of decoders: MAX9526, ADV7180, TVP5150,
OV7670 and AS0260.
The feature is available through *_tegra_camera_platform_data
struct initialised in board-*.c files.

Add GPIO keyboard platform device configuration. Currently only the power key
is defined which is registred as wake key as well in order to wake the SoC when

Clean-up GPIO definitions and names (e.g. use LVDS_ defines, BKL1_ON
rather than BL_ON and HDMI1_HPD rather than hdmi_hpd).
|
|
Up to now only the LVDS transceiver controlling GPIOs were exported.
This patch adds the generic Apalis GPIOs to the list of via sysfs to
userspace exported ones as well.

Initialisation of the framebuffer console on DVI-D aka HDMI sometimes
failed. This was particularly bad on Apalis T30 where this is activated
by default. On Colibri T30 this was observed when enabling it using the
fbcon=map:1 boot argument.
This fix curtsey of Bibek Basu from NVIDIA explicitly enables PLLA
during early clock initialisation which avoids a later race with the
display driver on DC1.

If the local critical temperature is reached the power is
unconditionally switched off. At 70°C ambient the default of 85°C
can be reached. So increase the limit in the hwmon chip to 95°C.

Enable PCI quirk support resp. don't explicitly disable it in order for
the following fix to take effect.
The Apalis evaluation board needs to set the link speed to 2.5 GT/s
(GEN1). The default link speed setting is 5 GT/s (GEN2). 0x98 is the
Link Control 2 PCIe Capability Register of the PEX8605 PCIe switch. The
switch supports link speed auto negotiation, but falsely sets the link
speed to 5 GT/s.
