[PATCH v4 0/8] drm/vc4: hdmi: Support the 10/12 bit output

Hi,

Here's some patches to enable the HDR output in the RPi4/BCM2711 HDMI
controller.

Let me know what you think,
Maxime

Changes from v3:
  - Don't dereference the connector->state pointer if kzalloc failed

Changes from v2:
  - Rebased on current drm-misc-next
  - Fixed a bug that was dropping the refresh rate when the bpc count
    was increased

Changes from v1:
  - Added the coccinelle script to the first patch
  - Fixed the pixel_rate ramp up

Maxime Ripard (8):
  drm/vc4: hvs: Align the HVS atomic hooks to the new API
  drm/vc4: Pass the atomic state to encoder hooks
  drm/vc4: hdmi: Don't access the connector state in reset if kmalloc
    fails
  drm/vc4: hdmi: Create a custom connector state
  drm/vc4: hdmi: Store pixel frequency in the connector state
  drm/vc4: hdmi: Use the connector state pixel rate for the PHY
  drm/vc4: hdmi: Limit the BCM2711 to the max without scrambling
  drm/vc4: hdmi: Enable 10/12 bpc output
