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>;
				};
			};
	};
