[PATCH v4 05/10] drm: arc: Use crtc->mode_valid() callback

[Alexey Brodkin]

Hi Jose,

The only nitpicking note from my side is patch name.

Probably full driver name as "arcpgu" might give a bit more context
especially if later something else from ARC appears in "drm" folder.
But IMHO that doesn't worth another respin.
