Subject: [PATCH] drm/vc4: plane: Move planes creation to its own
|
|
function
|
|
|
|
The planes so far were created as part of the CRTC binding code with
|
|
each planes created associated only to one CRTC. However, the hardware
|
|
in the vc4 doesn't really have such constraint and can be used with any
|
|
CRTC.
|
|
|
|
In order to rework this, let's first move the overlay and cursor planes
|
|
creation to a function of its own.
