[PATCH v4 5/7] drm/tilcdc: Call drm_crtc_vblank_on() and *_off() in start() and stop()

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

 



Add drm_crtc_vblank_on() and *_off() calls to start() and stop()
functions, to make sure any vblank waits etc. gets properly cleaned
up.
