-Samsung S5C73M3 8Mp camera ISP
-------------------------------
-
-The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656) video
-data busses. The I2C bus is the main control bus and additionally the SPI bus
-is used, mostly for transferring the firmware to and from the device. Two
-slave device nodes corresponding to these control bus interfaces are required
-and should be placed under respective bus controller nodes.
-
-I2C slave device node
----------------------
-
-Required properties:
-
-- compatible : "samsung,s5c73m3";
-- reg : I2C slave address of the sensor;
-- vdd-int-supply : digital power supply (1.2V);
-- vdda-supply : analog power supply (1.2V);
-- vdd-reg-supply : regulator input power supply (2.8V);
-- vddio-host-supply : host I/O power supply (1.8V to 2.8V);
-- vddio-cis-supply : CIS I/O power supply (1.2V to 1.8V);
-- vdd-af-supply : lens power supply (2.8V);
-- xshutdown-gpios : specifier of GPIO connected to the XSHUTDOWN pin;
-- standby-gpios : specifier of GPIO connected to the STANDBY pin;
-- clocks : should contain list of phandle and clock specifier pairs
- according to common clock bindings for the clocks described
- in the clock-names property;
-- clock-names : should contain "cis_extclk" entry for the CIS_EXTCLK clock;
-
-Optional properties:
-
-- clock-frequency : the frequency at which the "cis_extclk" clock should be
- configured to operate, in Hz; if this property is not
- specified default 24 MHz value will be used.
-
-The common video interfaces bindings (see video-interfaces.txt) should be used
-to specify link from the S5C73M3 to an external image data receiver. The S5C73M3
-device node should contain one 'port' child node with an 'endpoint' subnode for
-this purpose. The data link from a raw image sensor to the S5C73M3 can be
-similarly specified, but it is optional since the S5C73M3 ISP and a raw image
-sensor are usually inseparable and form a hybrid module.
-
-Following properties are valid for the endpoint node(s):
-
-endpoint subnode
-----------------
-
-- data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in
- video-interfaces.txt. This sensor doesn't support data lane remapping
- and physical lane indexes in subsequent elements of the array should
- be only consecutive ascending values.
-
-SPI device node
----------------
-
-Required properties:
-
-- compatible : "samsung,s5c73m3";
-
-For more details see description of the SPI busses bindings
-(../spi/spi-bus.txt) and bindings of a specific bus controller.
-
-Example:
-
-i2c@138a000000 {
- ...
- s5c73m3@3c {
- compatible = "samsung,s5c73m3";
- reg = <0x3c>;
- vdd-int-supply = <&buck9_reg>;
- vdda-supply = <&ldo17_reg>;
- vdd-reg-supply = <&cam_io_reg>;
- vddio-host-supply = <&ldo18_reg>;
- vddio-cis-supply = <&ldo9_reg>;
- vdd-af-supply = <&cam_af_reg>;
- clock-frequency = <24000000>;
- clocks = <&clk 0>;
- clock-names = "cis_extclk";
- xshutdown-gpios = <&gpf1 3 1>;
- standby-gpios = <&gpm0 1 1>;
- port {
- s5c73m3_ep: endpoint {
- remote-endpoint = <&csis0_ep>;
- data-lanes = <1 2 3 4>;
- };
- };
- };
-};
