+Texas Instruments VPIF Capture
+------------------------------
+
+The TI Video Port InterFace (VPIF) capture component is the primary
+component for video capture on some TI DaVinci family SoCs.
+
+TI Document number reference: SPRUH82C
+
+Required properties:
+- compatible: must be "ti,vpif-capture"
+- reg: physical base address and length of the registers set for the device;
+- interrupts: should contain IRQ line for the VPIF
+
+VPIF capture has a 16-bit parallel bus input, supporting 2 8-bit
+channels or a single 16-bit channel. It should contain at least one
+port child node with child 'endpoint' node. Please refer to the
+bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example using 2 8-bit input channels, one of which is connected to an
+I2C-connected TVP5147 decoder:
+
+ vpif_capture: video-capture@0x00217000 {
+ compatible = "ti,vpif-capture";
+ reg = <0x00217000 0x1000>;
+ interrupts = <92>;
+
+ port {
+ vpif_ch0: endpoint@0 {
+ reg = <0>;
+ bus-width = <8>;
+ remote-endpoint = <&composite>;
+ };
+
+ vpif_ch1: endpoint@1 {
+ reg = <1>;
+ bus-width = <8>;
+ data-shift = <8>;
+ };
+ };
+ };
+
+[ ... ]
+
+&i2c0 {
+
+ tvp5147@5d {
+ compatible = "ti,tvp5147";
+ reg = <0x5d>;
+ status = "okay";
+
+ port {
+ composite: endpoint {
+ hsync-active = <1>;
+ vsync-active = <1>;
+ pclk-sample = <0>;
+
+ /* VPIF channel 0 (lower 8-bits) */
+ remote-endpoint = <&vpif_ch0>;
+ bus-width = <8>;
+ };
+ };
+ };
+
+};
