Add support for HDR metadata using the hdr_output_metadata connector property, configure Dynamic Range and Mastering InfoFrame accordingly.
A use_drm_infoframe flag is added to dw_hdmi_plat_data that platform drivers can use to signal when Dynamic Range and Mastering infoframes is supported. This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version, and only GXL support DRM InfoFrame.
The first patch add functionality to configure DRM InfoFrame based on the hdr_output_metadata connector property.
The remaining patches sets the use_drm_infoframe flag on some SoCs supporting Dynamic Range and Mastering InfoFrame.
v2 has been runtime tested on a Rock64 (RK3328) and Rock Pi 4 (RK3399), only build tested for Amlogic and Allwinner.
Changes in v2:
- address comments from Andrzej Hajda
- renamed blob_equal to hdr_metadata_equal
- renamed drm_infoframe flag to use_drm_infoframe
- use hdmi_drm_infoframe_pack and a loop to write regs
- remove hdmi version check in hdmi_config_drm_infoframe
