[PATCH 0/7] Exynos4: enable HDMI support for Odroid and UniversalC210

[Marek Szyprowski]

Hello,

This is a long awaited patch series enabling support for HDMI output
available on Exynos4412-based Odroid boards (X/X2/U2/U3/U3+) and
Exynos4210 Universal C210 board.

This patch consists of 3 groups of patches, which are aimed to be merged
to respective maintainer kernel trees.

First patch ("clk: exynos4: add support for MOUT_HDMI and MOUT_MIXER
clocks") adds missing device tree support for hdmi related clocks. It is
prepared for clk kernel tree.

Next two patches ("drm: exynos: hdmi: make 'hdmi-en' regulator optional
and keep it enabled" and "drm: hdmi/mixer: enable exynos 4210 and 4x12
soc support") add proper support for Exynos4 SoCs to Exynos DRM drivers.
Those patches should go to exynos-drm kernel tree.

Last patches ("Exynos: add support for 'domain-always-on' property",
"ARM: dts: exynos4: add hdmi related nodes", "ARM: dts:
exynos4412-odroid: enable hdmi support" and "ARM: dts:
exynos4210-universal_c210: enable hdmi support") adds changes to all DTS
files and adds 'domain-always-on' property to Exynos power-domain
driver. This property is needed to resolve the non-trivial dependences
between TV and LCD0 power domains and the power on/off sequence of the
TV and mixer modules.

Patches are prepared on top of v3.16-rc3 with '[PATCH v2 0/4] Add
Exynos4412 based Odroid X2 and U2/U3/U3+ support' series and '[PATCH]
ARM: dts: exynos4412-odroid: add support for GPIO buttons' patch
applied:

Kernel tree with all Odroid related patches is available at
http://git.linaro.org/git-ro/people/marek.szyprowski/linux-srpol.git
on v3.16-odroid branch.
