Subject: [PATCH] drm/vc4: crtc: Introduce a lower-level crtc init
|
|
helper

The current vc4_crtc_init() helper assumes that we will be using
|
|
hardware planes and calls vc4_plane_init().
|
|
|
|
While it's a reasonable assumption, we'll want to mock the plane and
|
|
thus provide our own. Let's create a helper that will take the plane as
|
|
an argument.
