Hi Paul,

The conversion of rockchip-rga.txt to rockchip-rga.yaml by myself just
has been approved by robh.
Maybe place dts patches at the end of a patch serie.
Could you include a &rga patch if your device is supported in mainline,
so we can test with:
make ARCH=arm64 dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-rga.yaml
