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
