-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);
-- stbyn-gpios	  : GPIO connected to STDBYN pin;
-- rstn-gpios	  : GPIO connected to RSTN pin;
-- clocks	  : list of phandle and clock specifier pairs
-		    according to common clock bindings for the
-		    clocks described in clock-names;
-- clock-names	  : should include "mclk" for the sensor's master clock;
-
-Optional properties:
-
-- clock-frequency : the frequency at which the "mclk" clock should be
-		    configured to operate, in Hz; if this property is not
-		    specified default 24 MHz value will be used.
-
-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) specifies MIPI CSI-2 data lanes as covered in
-	       video-interfaces.txt. If present it should be <1> - the device
-	       supports only one data lane without re-mapping.
-
-Example:
-
-s5k5bafx@2d {
-	compatible = "samsung,s5k5baf";
-	reg = <0x2d>;
-	vdda-supply = <&cam_io_en_reg>;
-	vddreg-supply = <&vt_core_15v_reg>;
-	vddio-supply = <&vtcam_reg>;
-	stbyn-gpios = <&gpl2 0 1>;
-	rstn-gpios = <&gpl2 1 1>;
-	clock-names = "mclk";
-	clocks = <&clock_cam 0>;
-	clock-frequency = <24000000>;
-
-	port {
-		s5k5bafx_ep: endpoint {
-			remote-endpoint = <&csis1_ep>;
-			data-lanes = <1>;
-		};
-	};
-};
