Atmel Image Sensor Interface (ISI) SoC Camera Subsystem
----------------------------------------------

Required properties:
- compatible: must be "atmel,at91sam9g45-isi"
- reg: physical base address and length of the registers set for the device;
- interrupts: should contain IRQ line for the ISI;
- clocks: list of clock specifiers, corresponding to entries in
          the clock-names property;
- clock-names: must contain "isi_clk", which is the isi peripherial clock.

ISI 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:
	isi: isi@f0034000 {
		compatible = "atmel,at91sam9g45-isi";
		reg = <0xf0034000 0x4000>;
		interrupts = <37 IRQ_TYPE_LEVEL_HIGH 5>;

		clocks = <&isi_clk>;
		clock-names = "isi_clk";

		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_isi>;

		port {
			#address-cells = <1>;
			#size-cells = <0>;

			isi_0: endpoint {
				remote-endpoint = <&ov2640_0>;
				bus-width = <8>;
			};
		};
	};

	i2c1: i2c@f0018000 {
		ov2640: camera@0x30 {
			compatible = "ovti,ov2640";
			reg = <0x30>;

			port {
				ov2640_0: endpoint {
					remote-endpoint = <&isi_0>;
					bus-width = <8>;
				};
			};
		};
	};
