[PATCH v3 0/5] ARM: dts: enable hdmi for exynos5 based peach and snow boards

[PATCH v3 0/5] 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.

V3:
1) Re-spin on dependent patches.
2) Added patch to enable hdmi for Peach-pi board.

V2:
1) Re-spin on dependent patches.
2) Added patch to remove chip specific hdmi hpd gpio from
board file top SoC file.

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

It is dependent on
1) Arun's patch for adding peach-pit board dts file at
http://www.spinics.net/lists/linux-samsung-soc/msg30103.html. [Patch is 'ACK'ed.]
2) Sachin's patch for snow board dts file at
https://patches.linaro.org/28325/
3) DRM Hdmi driver patch which is changing the DT binding at
http://www.spinics.net/lists/linux-samsung-soc/msg28052.html
4) Arun's patches for basic Exynos5800 support, available at
http://comments.gmane.org/gmane.linux.kernel.samsung-soc/30667
[Already Applied in Kukjin's v3.16-next/soc-exynos]
