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 {
ov7740: camera@21 {
compatible = "ovti,ov7740";
reg = <0x21>;
clocks = <&isc>;
clock-names = "xvclk";
assigned-clocks = <&isc>;
assigned-clock-rates = <24000000>;
port {
ov7740_0: endpoint {
remote-endpoint = <&isc_0>;
};
};
};
};
