It's designed to be low-power, posesses some features such as a programmable comb-filter, and automatic input standard detection. Signed-off-by: Maxime Chevallier --- V2->V3 : Fix the example not compiling due to a typo in the reset-gpios node. V3->V4 : Add the missing reset-gpios node to the binding V4->V5 : Renamed the file to match the compatible string, and referenced the graph.yaml schema .../bindings/media/i2c/techwell,tw9900.yaml | 63 +++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/techwell,tw9900.yaml diff --git a/Documentation/devicetree/bindings/media/i2c/techwell,tw9900.yaml b/Documentation/devicetree/bindings/media/i2c/techwell,tw9900.yaml new file mode 100644 index 000000000000..b5047c26f0cb --- /dev/null +++ b/Documentation/devicetree/bindings/media/i2c/techwell,tw9900.yaml @@ -0,0 +1,63 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/i2c/techwell,tw9900.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Techwell TW9900 NTSC/PAL/SECAM video decoder + +maintainers: + - Maxime Chevallier + +description: + The tw9900 is a multi-standard video decoder, supporting NTSC, PAL and SECAM + standards with auto-detection features. + +properties: + compatible: + items: + - enum: + - techwell,tw9900 + + reg: + maxItems: 1 + + vdd-supply: + description: VDD power supply + + reset-gpios: + description: GPIO descriptor for the RESET input pin + maxItems: 1 + + port: + $ref: /schemas/graph.yaml#/properties/port + description: + Video port for the decoder output. + +additionalProperties: false + +required: + - compatible + - reg + +examples: + - | + #include + i2c { + #address-cells = <1>; + #size-cells = <0>; + + tw9900: tw9900@44 { + compatible = "techwell,tw9900"; + reg = <0x44>; + + vdd-supply = <&tw9900_supply>; + reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>; + + port { + tw9900_out: endpoint { + remote-endpoint = <&vip_in>; + }; + }; + }; + }; -- 2.25.4
