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 Jonas Karlman (4): drm/bridge: dw-hdmi: Add Dynamic Range and Mastering InfoFrame support drm/rockchip: Enable DRM InfoFrame support on RK3328 and RK3399 drm/meson: Enable DRM InfoFrame support on GXL, GXM and G12A drm/sun4i: Enable DRM InfoFrame support on H6 drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 81 +++++++++++++++++++++ drivers/gpu/drm/bridge/synopsys/dw-hdmi.h | 37 ++++++++++ drivers/gpu/drm/meson/meson_dw_hdmi.c | 5 ++ drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 2 + drivers/gpu/drm/sun4i/sun8i_dw_hdmi.c | 2 + drivers/gpu/drm/sun4i/sun8i_dw_hdmi.h | 1 + include/drm/bridge/dw_hdmi.h | 1 + 7 files changed, 129 insertions(+) -- 2.17.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
