The usual drm driver has tons of different drm_mm memory managers so the drm
error message in dmesg is pretty useless. WARN instead so that we have the full

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.
