[PATCH 27/38] drm: rcar-du: Switch connector DPMS to atomic helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The atomic connector DPMS helper implements the connector DPMS operation
using atomic commit, removing the need for DPMS helper operations on
CRTCs and encoders.
