[PATCH v5 17/69] drm/vc4: plane: Take possible_crtcs as an argument

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

 



vc4_plane_init() currently initialises the plane with no possible CRTCs,
and will expect the caller to set it up by itself.

Let's change that logic a bit to follow the syntax of
drm_universal_plane_init() and pass the possible CRTCs bitmask as an
argument to the function instead.
