This patchset is based on Boris's v10 "drm: Add support for bus-format negotiation" at [1] patchset to implement full bus-format negotiation for DW-HDMI, including YUV420 support and 10/12/16bit YUV444, YUV422 and RGB. The Color Space Converter support is already implemented.
And the counterpart implementation in the Amlogic Meson VPU dw-hdmi glue : - basic bus-format negotiation to select YUV444 bus-format as DW-HDMI input - YUV420 support when HDMI2.0 YUV420 modeset
This is a follow-up from the previous attempts : - "drm/meson: Add support for HDMI2.0 YUV420 4k60" at [2] - "drm/meson: Add support for HDMI2.0 4k60" at [3]
Changes sincd v3 at [6]: - Added "Plug atomic state hooks to the default implementation" on drm/bridge: dw-hdmi - Also added these atomic state hooks in meson-dw-hdmi in patch 7 - Rebased on latest drm-misc-next including patches 1-7 of [1]
Changes since RFC v2 at [5]: - Added fixes from Jonas, who tested and integrated it for Rockchip SoCs - Added support for 10/12/16bit tmds clock calculation - Added support for max_bcp connector property - Adapted to Boris's v4 patchset - Fixed typos reported by boris
Changes since RFC v1 at [4]: - Rewrote negociation using the v2 patchset, including full DW-HDMI fmt negociation
