1Atmel Image Sensor Interface (ISI) SoC Camera Subsystem
2----------------------------------------------
3
4Required properties:
5- compatible: must be "atmel,at91sam9g45-isi"
6- reg: physical base address and length of the registers set for the device;
7- interrupts: should contain IRQ line for the ISI;
8- clocks: list of clock specifiers, corresponding to entries in
9          the clock-names property;
10- clock-names: must contain "isi_clk", which is the isi peripherial clock.
11
12ISI supports a single port node with parallel bus. It should contain one
13'port' child node with child 'endpoint' node. Please refer to the bindings
14defined in Documentation/devicetree/bindings/media/video-interfaces.txt.

16Example:
17	isi: isi@f0034000 {
18		compatible = "atmel,at91sam9g45-isi";
19		reg = <0xf0034000 0x4000>;
20		interrupts = <37 IRQ_TYPE_LEVEL_HIGH 5>;
21
22		clocks = <&isi_clk>;
23		clock-names = "isi_clk";
24
25		pinctrl-names = "default";
26		pinctrl-0 = <&pinctrl_isi>;
27
28		port {
29			#address-cells = <1>;
30			#size-cells = <0>;
31
32			isi_0: endpoint {
33				remote-endpoint = <&ov2640_0>;
34				bus-width = <8>;
35			};
36		};
37	};
38
39	i2c1: i2c@f0018000 {
40		ov2640: camera@0x30 {
41			compatible = "omnivision,ov2640";
42			reg = <0x30>;
43
44			port {
45				ov2640_0: endpoint {
46					remote-endpoint = <&isi_0>;
47					bus-width = <8>;
48				};
49			};
50		};
