+
+description:
+ The Image Sensor Controller (ISC) device provides the video input capabilities for the
+ Atmel/Microchip AT91 SAMA family of devices.
+
+ The ISC has a single parallel input that supports RAW Bayer, RGB or YUV video,
+ with both external synchronization and BT.656 synchronization for the latter.

-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@...08000 {
- 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>;
