[PATCH v4 0/9] Enable HDMI support on Exynos platforms

[Marek Szyprowski]

Hi all,

This is yet another approach to submit patches, which enables HDMI
support for two Exynos based platforms: UniversalC210 and Odroid X2/U3.

Beside DTS changes, this patchset adds parent domain support for Exynos
PM domains. This was the most controversial patch in the previous
attempts, but I hope I fixes all reported issues and made it really
generic. For more details see individual patches.

The patchset is based on my previous patch:
'ARM: DTS: Exynos: convert to generic power domain bindings'
(http://www.spinics.net/lists/linux-samsung-soc/msg40584.html)
and 'PM / Domains: Export of_genpd_get_from_provider function'
patch merged as commit 7496fcbe8a643097efc061160e1c3b65ee2fa350
to v3.19-rc4.

Thanks to Tobias Jakobi for testing and finding out that the already
merged exynos4 clocks hierarchy fixup (commit
df019a5c0f7083001cb694f44821ca506425bda2 'clk: samsung: exynos4: set
parent of sclk_hdmiphy to hdmi') doesn't work in all cases. To finlly
solve the power on/off issues I've decided to simply add 'hdmi' clock
handling also to mixer module.

Regards
Marek Szyprowski
