[PATCH 3/8] drm: bridge: dw_hdmi: Fold poweron and setup functions

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

 



Fold the poweron and setup functions into one function and use the
adjusted_mode directly from the new crtc_state to remove the need of
storing previous_mode.
