[PATCH v5 0/9] Enable HDMI support on Exynos platforms

[Marek Szyprowski]

Hi all,

This is yet another update on patchset, which enables HDMI support for
Exynos based platforms.

Beside DTS changes, this patchset adds parent domain support for Exynos
PM domains and add support for 'hdmi' clock directly to Exynos DRM mixer
driver.

The patchset is based on samsung/for-next branch and 'PM / Domains:
Export of_genpd_get_from_provider function' patch merged as commit
7496fcbe8a643097efc061160e1c3b65ee2fa350 to v3.19-rc4.

Regards
Marek Szyprowski
