[PATCH 0/7] ARM: dts: enable hdmi for exynos5 based peach and snow boards

[Rahul Sharma]

From: Rahul Sharma <Rahul.Sharma@samsung.com>

Enable hdmi for exynos5250 based snow board and exynos5420
based peach pit board. It also adds properties to hdmi nodes
for accessing hdmiphy as simple phys.

This series is based on Kukjin Kims, for-next branch.

It is dependent on
1) Tomasz Stanislawski's Simple phy driver patches at
https://lkml.org/lkml/2014/4/8/226.
2) Arun's patch for adding peach-pit board dts file at
http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg28846.html.

Looks like tps65090_fet7 is not defined yet or might be not mentioned as
dependency.
