+Atmel Image Sensor Interface (ISI)
+----------------------------------
+
+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".
+- pinctrl-names, pinctrl-0: please refer to pinctrl-bindings.txt.
+
+ISI supports a single port node with parallel bus. It shall 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";
+Endpoint node properties
+------------------------
 
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_isi>;
+- bus-width: <8> or <10> (mandatory)
+- hsync-active (default: active high)
+- vsync-active (default: active high)
+- pclk-sample (default: sample on falling edge)
+- remote-endpoint: A phandle to the bus receiver's endpoint node (mandatory).
