From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

Document the device tree bindings for this driver.

Mostly copied from the atmel-isc bindings.

-Atmel Image Sensor Interface (ISI) SoC Camera Subsystem
-----------------------------------------------
+Atmel Image Sensor Interface (ISI)
+----------------------------------
 
-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.
+Required properties for ISI:
+- 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;
+	Please refer to clock-bindings.txt.
+- clock-names
+	Required elements: "isi_clk".
+- #clock-cells
+	Should be 0.
+- pinctrl-names, pinctrl-0
+	Please refer to pinctrl-bindings.txt.
 
 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";
+isi: isi@f0034000 {
+	compatible = "atmel,at91sam9g45-isi";
+	reg = <0xf0034000 0x4000>;
+	interrupts = <37 IRQ_TYPE_LEVEL_HIGH 5>;
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_isi_data_0_7>;
+	clocks = <&isi_clk>;
+	clock-names = "isi_clk";
+	status = "ok";
+	port {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		isi_0: endpoint {
+			reg = <0>;
+			remote-endpoint = <&ov2640_0>;
+			bus-width = <8>;
+			vsync-active = <1>;
+			hsync-active = <1>;
+		};
+	};
+};
+
+i2c1: i2c@f0018000 {
+	status = "okay";
 
+	ov2640: camera@0x30 {
+		compatible = "ovti,ov2640";
+		reg = <0x30>;
 		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_isi>;
