-Samsung S5K5BAF UXGA 1/5" 2M CMOS Image Sensor with embedded SoC ISP
--------------------------------------------------------------
-
-Required properties:
-
-- compatible : "samsung,s5k5baf";
-- reg : i2c slave address of the sensor;
-- vdda-supply : analog power supply 2.8V (2.6V to 3.0V);
-- vddreg-supply : regulator input power supply 1.8V (1.7V to 1.9V)
- or 2.8V (2.6V to 3.0);
-- vddio-supply : I/O power supply 1.8V (1.65V to 1.95V)
- or 2.8V (2.5V to 3.1V);
-- gpios : GPIOs connected to STDBYN and RSTN pins,
- in order: STBYN, RSTN;
-- clock-frequency : master clock frequency in Hz;
-
-Optional properties:
-
-- clocks : contains the sensor's master clock specifier;
-- clock-names : contains "mclk" entry;
-- samsung,hflip : horizontal image flip;
-- samsung,vflip : vertical image flip;
-
-The device node should contain one 'port' child node with one child 'endpoint'
-node, according to the bindings defined in Documentation/devicetree/bindings/
-media/video-interfaces.txt. The following are properties specific to those nodes.
-
-endpoint node
--------------
-
-- data-lanes : (optional) an array specifying active physical MIPI-CSI2
- data output lanes and their mapping to logical lanes; the
- array's content is unused, only its length is meaningful;
-
-Example:
-
-s5k5bafx@2d {
- compatible = "samsung,s5k5baf";
- reg = <0x2d>;
- vdda-supply = <&cam_io_en_reg>;
- vdd_reg-supply = <&vt_core_15v_reg>;
- vddio-supply = <&vtcam_reg>;
- gpios = <&gpl2 0 1>,
- <&gpl2 1 1>;
- clock-frequency = <24000000>;
-
- port {
- s5k5bafx_ep: endpoint {
- remote-endpoint = <&csis1_ep>;
- data-lanes = <1>;
- };
- };
-};
