41d8bdf67c ARM: dts: Update for pinctrl-samsung driver for exynos4210-origen
This patch updates all parts of Origen dts related to pin configuration
to use new GPIO and pinctrl bindings, instead of (now unsupported on
Exynos4) legacy gpio-samsung bindings.

34db4990e0 ARM: dts: Add aliases for i2c controller for exynos4
This is similar to a recent commit for exynos5250 titled:
  ARM: EXYNOS: Add aliases for i2c controller

Adding aliases will be useful to prevent warnings in a future
change. See:
  i2c: s3c2410: Get the i2c bus number from alias id

95e82941b7 ARM: dts: Add board dts file for Snow board (ARM Chromebook)
This dts file is based on the Snow dts file in the Chromium OS kernel
tree with the following changes:
* Some details have been updated to match the exynos5250-smdk5250.dts
  file from linux-next (as of c11068538994430547722dc9fb515a0ceefd5cb9).
* This file doesn't include references to hardware whose upstream
  support isn't quite there yet.  That includes most i2c devices.
  Note that most i2c busses have been included with no devices.

The Snow dts file is mostly just an include of the "cros5250" dts file
which describes a class of similar boards. Support for other boards has
not yet been send upstream.

With this file and a change to use UART3 for serial output I can:
* Boot to a command line using either SD or EMMC as a root filesystem
* See the power button and lid switch using evtest.

eef6fcaa42 ARM/dts: omap3: Fix mcbsp2/3 hwmods to be able to probe the drivers for audio
Fixes the following errors:

[    2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel

Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.

3d76f9f5d3 ARM: dts: imx6q-arm2: move NANDF_CS pins out of 'hog'
Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet)
defines NANDF_CS pins as gpio in 'hog', assuming these two pins are
always used by usdhc3 in gpio mode as card-detection and
write-protection on ARM2 board.  But it's not true.  These pins are
shared by usdhc3 and gpmi-nand.  We should have the pins functional
for gpmi-nand when usdhc3 is disabled.

Move the pins out of 'hog', so that pins only work in gpio mode as CD
and WP when usdhc3 is enabled, and otherwise they are available for
gpmi-nand.

a04b07c0fc pinctrl: samsung: Use per-bank IRQ domain for wake-up interrupts
This patch reworks wake-up interrupt handling in pinctrl-exynos driver,
so each pin bank, which provides wake-up interrupts, has its own IRQ
domain.

Information about whether given pin bank provides wake-up interrupts,
how many and whether they are separate or muxed are parsed from device
tree.

It gives following advantages:
  - interrupts can be specified in device tree in a more readable way,
    e.g. :
    	device {
		/* ... */
		interrupt-parent = <&gpx2>;
		interrupts = <4 0>;
		/* ... */
	};
  - the amount and layout of interrupts is not hardcoded in the code
    anymore, but defined in SoC-specific structure
  - bank and pin of each wake-up interrupt can be easily identified, to
    allow operations, such as setting the pin to EINT function, from
    irq_set_type() callback

595be7268a pinctrl: exynos: Use one IRQ domain per pin bank
Instead of registering one IRQ domain for all pin banks of a pin
controller, this patch implements registration of per-bank domains.

At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts
of Exynos4x12) it simplifies driver code and device tree sources,
because GPIO interrupts can be now specified per banks.

Example:
	device {
		/* ... */
		interrupt-parent = <&gpa1>;
		interrupts = <3 0>;
		/* ... */
	};
