[PATCH v2 0/7] drm/vc4: Rework the HVS muxing code

[Maxime Ripard]

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
