[PATCH 0/4] exynos5250/hdmi: modify driver and arch data towards CCF migration

[PATCH 0/4] exynos5250/hdmi: modify driver and arch data towards CCF migration

[Rahul Sharma]

After switching to CCF, driver and device tree nodes are required
to be update with clock information. This set includes those changes.

After these patches, the only missing portion is hdmiphy power control
which is posted independently. Together, basic hdmi is working for
exynos5250.

[PATCH 4/4] ARM/dts: add clocks to hdmi dt node for exynos5250

[Rahul Sharma]

Fix wrong clock numbers in hdmi dt node. Removed hdmiphy
clock which was a dummy clock earlier and not required now.
Also added mux clock to change the clock parent.
