[ Upstream commit ac67b07e268d46eba675a60c37051bb3e59fd201 ]
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines,
corresponding to the 80 status bits available in hardware. Each of these
lines can be configured as either an input or an output.
However, each of these GPIOs is actually an input *and* an output; we
actually have 80 inputs plus 80 outputs.
This change expands the maximum number of GPIOs to 160; the lower half
of this range are the input-only GPIOs, the upper half are the outputs.
We fix the GPIO directions to correspond to this mapping.
This also fixes a bug when setting GPIOs - we were reading from the
input register, making it impossible to set more than one output GPIO.

The ast2600 is a new generation of SoC from ASPEED. Similarly to the
ast2400 and ast2500, it has a GPIO controller for it's 3.3V GPIO pins.
Additionally, it has a GPIO controller for 36 1.8V GPIO pins. We use
the ngpio property to differentiate between these controllers.

This commit extends the flags that can be used in GPIO specifiers to
indicate if a pull-up resistor or pull-down resistor should be
enabled.
While some pinctrl DT bindings already offer the capability of
configuring pull-up/pull-down resistors at the pin level, a number of
simple GPIO controllers don't have any pinmuxing capability, and
therefore do not rely on the pinctrl DT bindings.
Such simple GPIO controllers however sometimes allow to configure
pull-up and pull-down resistors on a per-pin basis, and whether such
resistors should be enabled or not is a highly board-specific HW
characteristic.
By using two additional bits of the GPIO flag specifier, we can easily
allow the Device Tree to describe which GPIOs should have their
pull-up or pull-down resistors enabled. Even though the two options
are mutually exclusive, we still need two bits to encode at least
three states: no pull-up/pull-down, pull-up, pull-down.

Pull Devicetree updates from Rob Herring:
"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.

From LPC18xx and LPC43xx User Manuals the GPIO controller consists of
the following weakly connected blocks:
* GPIO pin interrupt block at 0x40087000,
* GPIO GROUP0 interrupt block at 0x40088000,
* GPIO GROUP1 interrupt block at 0x40089000,
* GPIO port block at 0x400F4000.
While all 4 sub-controller blocks have their own I/O addresses, moreover
all 3 interrupt blocks are APB0 peripherals and high-speed GPIO block is
an AHB slave, according to the hardware manual interrupt controllers and
GPIO controller block are seen as a single device, all 4 sub-controllers
have the shared reset signal RGU #28 and the same shared clock to access
registers CLK_Mx_GPIO on CCU1.
The change adds descriptions of the currently missing interrupt controller
blocks found on GPIO controller, new added properties are 'reg-names',
'resets', 'interrupt-controller' and '#interrupt-cells', also the example
is updated to reflect the changes in device tree binding description.

On some SoCs(e.g. MX7ULP), GPIO clock is gatable and maybe
disabled by default. Users have to make sure it's enabled before
being able to access controller registers, otherwise an external
abort error may occur. Let's add the optional clocks property to
handle this case.
For ULP GPIO clock, it includes two separate clocks: one is for
GPIO controller Input/Output function clock while another is
GPIO port control clock for interrupt function.

In 2011 the commit bf859f84a19f
("gpio/dt: Refine GPIO device tree binding") introduced an
experimental BNF notation for defining a regular grammar for
the GPIO phandles used by different devices.
This was an interesting approach, and shows that we have long
nutured the idea to formally verify device tree files using
regular grammar.
Most if not all other bindings use natural language to define
the bindings, and the recent thinking for verifying device
tree files is to use JSON schemas in separate definitions.
Cut the BNF business and replace it with natural language
so that it becomes more human-readable for now.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.19 kernel cycle.
I don't know if anything in particular stands out. Maybe the Aspeed
coprocessor thing from Benji: Aspeed is doing baseboard management
chips (BMC's) for servers etc.
These Aspeed's are ARM processors that exist inside (I guess) Intel
servers, and they are moving forward to using mainline Linux in those.
This is one of the pieces of the puzzle to achive that. They are doing
OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/
Summary:
Core changes:
- Add a new API for explicitly naming GPIO consumers, when needed.
- Don't let userspace set values on input lines. While we do not
think anyone would do this crazy thing we better plug the hole
before someone uses it and think it's a nifty feature.
- Avoid calling chip->request() for unused GPIOs.
New drivers/subdrivers:
- The Mediatek MT7621 is supported which is a big win for OpenWRT and
similar router distributions using this chip, as it seems every
major router manufacturer on the planet has made products using
this chip: https://wikidevi.com/wiki/MediaTek_MT7621
- The Tegra 194 is now supported.
- The IT87 driver now supports IT8786E and IT8718F super-IO chips.
- Add support for Rockchip RK3328 in the syscon GPIO driver.
Driver changes:
- Handle the get/set_multiple() properly on MMIO chips with inverted
direction registers. We didn't have this problem until a new chip
appear that has get/set registers AND inverted direction bits, OK
now we handle it.
- A patch series making more error codes percolate upward properly
for different errors on gpiochip_lock_as_irq().
- Get/set multiple for the OMAP driver, accelerating these multiple
line operations if possible.
- A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
lines need to be grabbed by a co-processor for doing automated
tasks, sometimes they are available as GPIO lines. By adding an
explicit API in this driver we make it possible for the two line
consumers to coexist. (This work was made available on the
ib-aspeed branch, which may be appearing in other pull requests.)
- Implemented .get_direction() and open drain in the SCH311x driver.
- Continuing cleanup of included headers in GPIO drivers"

In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec
mute control, can also be used for general purpose. It is manipulated by
the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI
pins can also be set in the same way.
Currently this GRF GPIO controller only supports the mute pin. If needed
in the future, the HDMI pins support can also be added.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

The device can optionally supply an interrupt, hence document that.
Add required GPIO properties to the example (extracted from a patch by
Wolfram Sang).

Some i.MX SoCs have GPIO clock gate in CCM, accessing
GPIO registers needs to enable GPIO clock gate first,
i.MX GPIO driver will enable clock gate if there is
clock property in GPIO node of dtb, add optional property
to i.MX GPIO binding doc.
