[PATCH 1/2] ARM: dts: exynos: Move the dwmmc aliases from smdk5250 dts to exynos

[Doug Anderson]

The aliases for dwmmc were placed in the SMDK5250 dts file but really
should be common for all exynos5250 boards.  Move it to the common CPU
file.

[PATCH 2/2] ARM: dts: snow: Add board dts file for Snow board (ARM Chromebook)

[Doug Anderson]

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.

Kukjin, since your pull requests came in today, can you ack this and
I'll just apply it on top of your branches?

Hi Olof, yeah, I sent pull-request but there are some patches for dt and
exynos5440 stuff in my tree not sent yet. If you're ok, let me take this
with your ack.

Note, I will try to send out remained Samsung stuff before release -rc7 ;-)

Thanks.

Best regards,
Kgene.
