Add a documentation for the Rockchip Camera Interface binding. Signed-off-by: Mehdi Djait <mehdi.djait@xxxxxxxxxxx> --- v8=>v9: dropped the "Reviewed-by: Rob Herring <robh@xxxxxxxxxx>" because of the following changes: - changed the compatible to rk3066-cif: rk3066 is the earliest Rockchip SoC that uses cif and it is the first model starting the RK30 lineup. - adjusted the description - changed the node name to video-capture .../bindings/media/rockchip,rk3066-cif.yaml | 96 +++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/rockchip,rk3066-cif.yaml diff --git a/Documentation/devicetree/bindings/media/rockchip,rk3066-cif.yaml b/Documentation/devicetree/bindings/media/rockchip,rk3066-cif.yaml new file mode 100644 index 000000000000..be69e474ed26 --- /dev/null +++ b/Documentation/devicetree/bindings/media/rockchip,rk3066-cif.yaml @@ -0,0 +1,96 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/rockchip,rk3066-cif.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Rockchip CIF Camera Interface + +maintainers: + - Mehdi Djait <mehdi.djait@xxxxxxxxxxx> + +description: | + CIF is a camera interface present on some rockchip SoCs.
