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 v5:
- Fixed the connector->state access in the connector state reset
- Added the tags from Thomas and Dave
Changes from v4:
- Added the tags from Thomas
- Fixed an issue with the clock doubling
- Changed a comment to match the code being introduced
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 (9):
drm/vc4: hvs: Align the HVS atomic hooks to the new API
drm/vc4: Pass the atomic state to encoder hooks
drm/vc4: hdmi: Take into account the clock doubling flag in
atomic_check
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
