[PATCH 0/7] Enable HDMI support on Exynos platforms

[PATCH 0/7] Enable HDMI support on Exynos platforms

[Andrzej Hajda]

This set of patches enables HDMI support for two Exynos based platforms:
UniversalC210 and Odroid.
Beside DTS changes patchset adds parent domain support for Exynos PM domains
and small but critical change in mixer clock. For details see individual patches.

The patchset is based on v3.18-rc4.

Regards
Andrzej

[PATCH 1/7] clk: samsung: exynos4: set parent of mixer gate clock to hdmi

[Andrzej Hajda]

This dependency is not clearly documented, but it seems
mixer gate clock is not working without hdmi clock.
It causes system hangs during mixer access with disabled hdmi.

[PATCH 2/7] ARM: Exynos: add support for sub-power domains

[Andrzej Hajda]

From: Marek Szyprowski <m.szyprowski@samsung.com>

This patch adds support for making one power domain a sub-domain of
other domain. This is useful for modeling power dependences for devices
like TV Mixer or Camera ISP, which needs to have more than one power
domain enabled to be operational.

[PATCH 4/7] ARM: dts: exynos4: add dependency between TV and LCD0 power domains

[Andrzej Hajda]

From: Marek Szyprowski <m.szyprowski@samsung.com>

TV Mixer needs both TV and LCD0 domains enabled to be fully operational.
This dependency is modelled by making TV power domains a sub-domain of
LCD0 power domain.

[PATCH 1/7] clk: samsung: exynos4: set parent of sclk_hdmiphy to hdmi

[Andrzej Hajda]

sclk_hdmiphy clock is generated by HDMI-PHY and depends on hdmi gate clock.
The patch models this dependency using parent/child hirerarchy.

The patch fixes issue with system hangs during mixer device access, mixer uses
sclk_hdmiphy descendant clock.

Hi Tomasz,

This patch replaces the previous one [1], as it slightly better models
the clock tree/jungle.
