Hi,
Here's a second attempt at fixing the current issues we have with the
muxing code that results in a PV muxing its HVS muxing when only another
CRTC is modified by a state, or vblank timeouts when trying to wait for a
vblank on a single CRTC while another one is inactive but enabled.
Let me know what you think,
Maxime
Changes from v1:
- Dropped the code trying to access all the CRTCs (whether in the state
or not) state
Maxime Ripard (7):
drm/vc4: kms: Remove useless define
drm/vc4: kms: Rename NUM_CHANNELS
drm/vc4: kms: Split the HVS muxing check in a separate function
drm/vc4: kms: Document the muxing corner cases
drm/vc4: kms: Add functions to create the state objects
drm/vc4: kms: Store the unassigned channel list in the state
drm/vc4: kms: Don't disable the muxing of an active CRTC
