Subject[PATCH v12 08/11] media: staging: dt-bindings: add Rockchip ISP1 yaml bindings
Date
Add yaml DT bindings for Rockchip ISP1.

This was tested and verified with:
mv drivers/staging/media/rkisp1/Documentation/devicetree/bindings/media/rockchip-isp1.yaml Documentation/devicetree/bindings/media/
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-isp1.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-isp1.yaml

Signed-off-by: Helen Koike <helen.koike@collabora.com>
