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 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 (7): drm/vc4: hvs: Align the HVS atomic hooks to the new API drm/vc4: Pass the atomic state to encoder hooks 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
