+* Texas Instruments TVP5150 and TVP5151 video decoders
+
+The TVP5150 and TVP5151 are video decoders that convert baseband NTSC and PAL
+(and also SECAM in the TVP5151 case) video signals to either 8-bit 4:2:2 YUV
+with discrete syncs or 8-bit ITU-R BT.656 with embedded syncs output formats.
+
+Required Properties:
+- compatible: value must be "ti,tvp5150"
+- reg: I2C slave address
+
+Optional Properties:
+- powerdown-gpios: phandle for the GPIO connected to the PDN pin, if any.
+- reset-gpios: phandle for the GPIO connected to the RESETB pin, if any.
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+&i2c2 {
+	...
+	tvp5150@5c {
+			compatible = "ti,tvp5150";
+			reg = <0x5c>;
+			powerdown-gpios = <&gpio4 30 GPIO_ACTIVE_LOW>;
+			reset-gpios = <&gpio6 7 GPIO_ACTIVE_LOW>;
+
+			port {
+				tvp5150_1: endpoint {
+					remote-endpoint = <&ccdc_ep>;
+				};
+			};
+	};
+};
