Hi Philippe, Heiko, Maxime, Laurent, A bad negociation was detected on platforms not implementing a bridge on the encoder side, which has been fixed in this version. Could you check it doesn't break your platforms using dw-hdmi ? Especially patches 1-5. Thanks, Neil This patchset is based on Boris's merged "drm: Add support for bus-format negotiation" 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 since v4 at [7]: - Cleaned up patch 1 - Added comment on patch 2 - Added commit message on patch 3 - Fixed invalid negociation when encoder is not yet a bridge (seen on allwinner & rockchip platforms) on patch 4 - Fixed invalid defines, handled MEDIA_BUS_FMT_FIXED and cleaned negociation debug on patch 4 - Added tags on patch 5, 6 - Removed meson_venc_hdmi_encoder_get_out_bus_fmts on patch 7 - Add off-list r-b from Jernej Changes since 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 [2] https://patchwork.freedesktop.org/patch/msgid/20190520133753.23871-1-narmstrong@xxxxxxxxxxxx [3] https://patchwork.freedesktop.org/patch/msgid/1549022873-40549-1-git-send-email-narmstrong@xxxxxxxxxxxx [4] https://patchwork.freedesktop.org/patch/msgid/20190820084109.24616-1-narmstrong@xxxxxxxxxxxx [5] https://patchwork.freedesktop.org/patch/msgid/20190827081425.15011-1-narmstrong@xxxxxxxxxxxx [6] https://patchwork.freedesktop.org/patch/msgid/20191218154637.17509-1-narmstrong@xxxxxxxxxxxx [7] https://patchwork.freedesktop.org/patch/msgid/20200206191834.6125-1-narmstrong@xxxxxxxxxxxx Jonas Karlman (2): drm/bridge: dw-hdmi: set mtmdsclock for deep color drm/bridge: dw-hdmi: add max bpc connector property Neil Armstrong (9): drm/bridge: dw-hdmi: Plug atomic state hooks to the default implementation drm/bridge: synopsys: dw-hdmi: add bus format negociation drm/bridge: synopsys: dw-hdmi: allow ycbcr420 modes for >= 0x200a drm/meson: venc: make drm_display_mode const drm/meson: meson_dw_hdmi: add bridge and switch to drm_bridge_funcs drm/meson: dw-hdmi: stop enforcing input_bus_format 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 | 319 +++++++++++++++++++++- drivers/gpu/drm/meson/meson_dw_hdmi.c | 180 +++++++++--- 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 | 6 +- include/drm/bridge/dw_hdmi.h | 1 + 8 files changed, 544 insertions(+), 76 deletions(-) -- 2.22.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
