Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daein...

Feature summary:
Add S3C64XX SoC series support - S3C64XX SoC series are previous version
chips of Exynos SoC series. With this patch set, KMS driver of Exynos drm
supports those chips also.

Update device tree support - This patch set corrects compatible strings,
and adds Exynos5420 SoC support for hdmi subsystem.

Consider CCF (Common Clock Framework) support - With reference to CCF
support, it uses clock_prepare_enable/clock_disable_unprepare instead of
clk_enable/clk_disable for hdmi subsystem.

Big cleanups - This patch just removes unnecessary all debug logs.
