-Samsung S5K6A3(YX) raw image sensor
----------------------------------
-
-S5K6A3(YX) is a raw image sensor with MIPI CSI-2 and CCP2 image data interfaces
-and CCI (I2C compatible) control bus.
-
-Required properties:
-
-- compatible	: "samsung,s5k6a3";
-- reg		: I2C slave address of the sensor;
-- svdda-supply	: core voltage supply;
-- svddio-supply	: I/O voltage supply;
-- afvdd-supply	: AF (actuator) voltage supply;
-- gpios		: specifier of a GPIO connected to the RESET 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 "extclk" entry for the sensor's EXTCLK clock;
-
-Optional properties:
-
-- clock-frequency : the frequency at which the "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 to the image data receiver. The S5K6A3(YX) device
-node should contain one 'port' child node with an 'endpoint' subnode.
-
-Following properties are valid for the endpoint node:
-
-- data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in
-  video-interfaces.txt.  The sensor supports only one data lane.
