Krzysztof Kozlowski 34a2d5aaad ARM: dts: Remove duplicated I2C7 nodes in exynos5250-snow
The i2c_7 node (i2c@12CD0000) with LVDS bridge child node was put in
Exynos5250 Snow DTS file twice. Move the LVDS bridge to proper existing
i2c_7 node.

Javier Martinez Canillas 8cf5e6dc8d ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for exynos5250-snow
The Marvell mwifiex driver prevents the system to enter into a suspend
state if the card power is not preserved during a suspend/resume cycle.

So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow.

Add the keep-power-in-suspend Power Management property to the SDIO/MMC
node so the mwifiex suspend handler doesn't fail and the system is able
to enter into a suspend state.

Javier Martinez Canillas 038e409605 ARM: dts: Define stdout-path property for exynos5250-snow
The kernel can use as the default console a serial port if is defined
as stdout device in the Device Tree.

This allows a board to be booted without the need of having a console
parameter in the kernel command line.

Currently the Snow DTS has a bootargs in the /chosen node and this is
kept since users that don't have a serial console on this board might
be using it to have the boot log shown in the display. This will have
more precedence than the stdout-path but it's fine since is only used
when CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND is enabled.

Javier Martinez Canillas b07a27696b ARM: dts: Enable wifi power-on for exynos5250-snow
The Snow board has a MMC/SDIO wifi chip that is always powered but it
needs a power sequence involving a reset (active low) and an enable
(active high) pins. Both pins are marked as active low since the MMC
simple power sequence driver asserts the pins prior to the card power
up procedure and de-asserts the pins after the card has been powered.

So the reset line will be left de-asserted and the enable pin will be
left asserted.

The chip also needs an external 32kHz reference clock to be operational
that is by the MAX77686 PMIC clock.

Add a simple MMC power sequence provider for the wifi MMC/SDIO slot.

Javier Martinez Canillas e5e5c6d14e ARM: dts: Add power and lid GPIO keys pinctrl for exynos5250-snow
The Exynos5250 Snow Chromebook has GPIO keys for power and lid
so the SoC I/O pins have to be configured in external interrupt
mode. Currently, this is working without setting the pinctrl
lines but is better to set it explicitly instead of relying on
the previous state of the I/O pins.

The DTS snippets were taken from the downstream ChromeOS tree.

Linus Torvalds 6da314122d ARM: SoC DT updates for 3.19
The DT branch adds a lot of new stuff for additional SoC and board
 support. The branch is the largest one and contains 513 out of the
 total 972 non-merge arm-soc changesets for 3.19.
 
 Most of the changes are about enabling additional on-chip devices for
 existing machines, but there are also an unusual number of new SoC
 types being added this time:
 
 * AMLogic Meson8
 * ARM Realview in DT mode
 * Allwinner A80
 * Broadcom BCM47081
 * Broadcom Cygnus
 * Freescale LS1021A
 * Freescale Vybrid 500 series
 * Mediatek MT6592, MT8127, MT8135
 * STMicroelectronics STiH410
 * Samsung Exynos4415
 
 The level of support for the above differs widely, some are just
 stubs with nothing more than CPU, memory and a UART, but others
 are fairly complete. As usual, these get extended over time.
 
 There are also many new boards getting added, this is the
 list of model strings that are showing up in new dts files:
 
 * ARM RealView PB1176
 * Altera SOCFPGA Arria 10
 * Asus RT-N18U (BCM47081)
 * Buffalo WZR-1750DHP (BCM4708)
 * Buffalo WZR-600DHP2 (BCM47081)
 * Cygnus Enterprise Phone (BCM911360_ENTPHN)
 * D-Link DIR-665
 * Google Spring
 * IGEP COM MODULE Rev. G (TI OMAP AM/DM37x)
 * IGEPv2 Rev. F (TI OMAP AM/DM37x)

The device tree sent upstream for exynos5250-snow encoded the search
key as CAPSLK.  However in all ChromeOS kernels it is L_META.  One can
certainly have long debates about which it ought to be, but I'm
proposing setting it to L_META because:
* That's how _all_ ChromeOS kernels do it and will do it.
* There is no L_META key on the board, so it's nice to have.
* For those people who really want it to be caps lock, they can use
  xmodmap or somesuch.

The arbitrated bus is numbered 104 simply as a convenience to make it
easier for people poking around to guess that it might have something
to do with the physical bus 4.

The addition is split between the cros5250-common and the snow device
