1 Samsung S5C73M3 8Mp camera ISP
2 ------------------------------
4 The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656) video
5 data busses. The I2C bus is the main control bus and additionally the SPI bus
6 is used, mostly for transferring the firmware to and from the device. Two
7 slave device nodes corresponding to these control bus interfaces are required
8 and should be placed under respective bus controller nodes.
15 - compatible : "samsung,s5c73m3";
16 - reg : I2C slave address of the sensor;
17 - vdd-int-supply : digital power supply (1.2V);
18 - vdda-supply : analog power supply (1.2V);
19 - vdd-reg-supply : regulator input power supply (2.8V);
20 - vddio-host-supply : host I/O power supply (1.8V to 2.8V);
21 - vddio-cis-supply : CIS I/O power supply (1.2V to 1.8V);
22 - vdd-af-supply : lens power supply (2.8V);
23 - xshutdown-gpios : specifier of GPIO connected to the XSHUTDOWN pin;
24 - standby-gpios : specifier of GPIO connected to the STANDBY pin;
25 - clocks : should contain list of phandle and clock specifier pairs
26 according to common clock bindings for the clocks described
27 in the clock-names property;
28 - clock-names : should contain "cis_extclk" entry for the CIS_EXTCLK clock;
32 - clock-frequency : the frequency at which the "cis_extclk" clock should be
33 configured to operate, in Hz; if this property is not
34 specified default 24 MHz value will be used.
36 The common video interfaces bindings (see video-interfaces.txt) should be used
37 to specify link from the S5C73M3 to an external image data receiver. The S5C73M3
38 device node should contain one 'port' child node with an 'endpoint' subnode for
39 this purpose. The data link from a raw image sensor to the S5C73M3 can be
40 similarly specified, but it is optional since the S5C73M3 ISP and a raw image
41 sensor are usually inseparable and form a hybrid module.
43 Following properties are valid for the endpoint node(s):
48 - data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in
49 video-interfaces.txt. This sensor doesn't support data lane remapping
50 and physical lane indexes in subsequent elements of the array should
51 be only consecutive ascending values.

61 (../spi/spi-bus.txt) and bindings of a specific bus controller.
