[PATCH v4 0/9] drm/vc4: Turn the TXP into a CRTC

[Maxime Ripard]

Hi,

This is another part of the rpi4 HDMI series that got promoted to a
series of its own to try to reduce the main one.

This rework is needed since the bcm2711 used in the rpi4 has a more
complex routing in the HVS that doesn't allow to use a fairly simple
mapping like what was used before.

Since that mapping affects both the pixelvalves and the TXP, turning the
TXP into a CRTC just like pixelvalves are allows to deal with the
mapping in the CRTC states, which turns out to be pretty convenient.

Let me know what you think,
Maxime

Changes from v3:
  - Stripped the patches out of the main HDMI series
  - Change the bind order of the HVS to avoid a compatible check
  - Added Eric's tags
  - Rebased on top of drm-misc-next
