-Texas Instruments AM437x CAMERA (VPFE)
---------------------------------------
-
-The Video Processing Front End (VPFE) is a key component for image capture
-applications. The capture module provides the system interface and the
-processing capability to connect RAW image-sensor modules and video decoders
-to the AM437x device.
-
-Required properties:
-- compatible: must be "ti,am437x-vpfe"
-- reg: physical base address and length of the registers set for the device;
-- interrupts: should contain IRQ line for the VPFE;
-- ti,am437x-vpfe-interface: can be one of the following,
-	0 - Raw Bayer Interface.
-	1 - 8 Bit BT656 Interface.
-	2 - 10 Bit BT656 Interface.
-	3 - YCbCr 8 Bit Interface.
-	4 - YCbCr 16 Bit Interface.
-
-VPFE supports a single port node with parallel bus. It should contain one
-'port' child node with child 'endpoint' node. Please refer to the bindings
-defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Example:
-	vpfe: vpfe@f0034000 {
-		compatible = "ti,am437x-vpfe";
-		reg = <0x48328000 0x2000>;
-		interrupts = <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>;
-
-		pinctrl-names = "default", "sleep";
-		pinctrl-0 = <&vpfe_pins_default>;
-		pinctrl-1 = <&vpfe_pins_sleep>;
-
-		port {
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			vpfe0_ep: endpoint {
-				remote-endpoint = <&ov2659_1>;
-				ti,am437x-vpfe-interface = <0>;
-				bus-width = <8>;
-				hsync-active = <0>;
-				vsync-active = <0>;
-			};
-		};
-	};
-
-	i2c1: i2c@4802a000 {
-
-		ov2659@30 {
-			compatible = "ti,ov2659";
-			reg = <0x30>;
-
-			port {
-				ov2659_1: endpoint {
-					remote-endpoint = <&vpfe0_ep>;
-					bus-width = <8>;
-					mclk-frequency = <12000000>;
-				};
-			};
-	};
