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 since RFC v1 at [4]: - Rewrote negociation using the v2 patchset, including full DW-HDMI fmt negociation [1] https://patchwork.freedesktop.org/patch/msgid/20190826152649.13820-1-boris.brezillon@collabora.com [2] https://patchwork.freedesktop.org/patch/msgid/20190520133753.23871-1-narmstrong@baylibre.com [3] https://patchwork.freedesktop.org/patch/msgid/1549022873-40549-1-git-send-email-narmstrong@baylibre.com [4] https://patchwork.freedesktop.org/patch/msgid/20190820084109.24616-1-narmstrong@baylibre.com Neil Armstrong (8): drm/meson: venc: make drm_display_mode const drm/meson: meson_dw_hdmi: switch to drm_bridge_funcs drm/bridge: synopsys: dw-hdmi: add bus format negociation drm/meson: dw-hdmi: stop enforcing input_bus_format drm/bridge: dw-hdmi: allow ycbcr420 modes for >= 0x200a drm/meson: venc: add support for YUV420 setup drm/meson: vclk: add support for YUV420 setup drm/meson: Add YUV420 output support drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 251 +++++++++++++++++++++- drivers/gpu/drm/meson/meson_dw_hdmi.c | 164 +++++++++++--- drivers/gpu/drm/meson/meson_vclk.c | 93 ++++++-- drivers/gpu/drm/meson/meson_vclk.h | 7 +- drivers/gpu/drm/meson/meson_venc.c | 10 +- drivers/gpu/drm/meson/meson_venc.h | 4 +- drivers/gpu/drm/meson/meson_venc_cvbs.c | 3 +- include/drm/bridge/dw_hdmi.h | 1 + 8 files changed, 466 insertions(+), 67 deletions(-) -- 2.22.0
