+Atmel Image Sensor Controller (ISC)
+----------------------------------------------
+
+Required properties for ISC:
+- compatible
+ Must be "atmel,sama5d2-isc".
+- reg
+ Physical base address and length of the registers set for the device.
+- interrupts
+ Should contain IRQ line for the ISC.
+- clocks
+ List of clock specifiers, corresponding to entries in
+ the clock-names property;
+ Please refer to clock-bindings.txt.
+- clock-names
+ Required elements: "hclock", "iscck", "gck".
+- #clock-cells
+ Should be 0.
+- clock-output-names
+ Should be "isc-mck".
+- pinctrl-names, pinctrl-0
+ Please refer to pinctrl-bindings.txt.
+
+ISC 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:
+isc: isc@f0008000 {
+ compatible = "atmel,sama5d2-isc";
+ reg = <0xf0008000 0x4000>;
+ interrupts = <46 IRQ_TYPE_LEVEL_HIGH 5>;
+ clocks = <&isc_clk>, <&iscck>, <&isc_gclk>;
+ clock-names = "hclock", "iscck", "gck";
+ #clock-cells = <0>;
+ clock-output-names = "isc-mck";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_isc_base &pinctrl_isc_data_8bit &pinctrl_isc_data_9_10 &pinctrl_isc_data_11_12>;
+
+ port {
+ isc_0: endpoint {
+ remote-endpoint = <&ov7740_0>;
+ hsync-active = <1>;
+ vsync-active = <0>;
+ pclk-sample = <1>;
+ };
+ };
+};
+
+i2c1: i2c@fc028000 {
