This patch adds subdev driver for Samsung S5K4E5 raw image sensor.
Like s5k6a3, it is also another fimc-is firmware controlled
sensor. This minimal sensor driver doesn't do any I2C communications
as its done by ISP firmware. It can be updated if needed to a
regular sensor driver by adding the I2C communication.

+* Samsung S5K4E5 Raw Image Sensor
+
+S5K4E5 is a raw image sensor with maximum resolution of 2560x1920
+pixels. Data transfer is carried out via MIPI CSI-2 port and controls
+via I2C bus.
+
+Required Properties:
+- compatible : must be "samsung,s5k4e5"
+- reg : I2C device address
+- reset-gpios : specifier of a GPIO connected to the RESET pin
+- clocks : should contain the sensor's EXTCLK clock specifier, from
+ the common clock bindings
+- clock-names : should contain "extclk" entry
+- svdda-supply : core voltage supply
+- svddio-supply: I/O voltage supply
+
+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 device node should be added to respective control bus controller
+(e.g. I2C0) nodes and linked to the csis port node, using the common
+video interfaces bindings, defined in video-interfaces.txt.
+
+Example:
+
+ i2c-isp@1313 {
+ s5k4e5@20 {
+ compatible = "samsung,s5k4e5";
+ reg = <0x20>;
+ reset-gpios = <&gpx1 2 1>;
+ clock-frequency = <2400>;
+ clocks = <&clock 129>;
+ clock-names = "extclk"
+ svdda-supply = <...>;
+ svddio-supply = <...>;
+ port {
+ is_s5k4e5_ep: endpoint {
+ data-lanes = <1 2 3 4>;
+ remote-endpoint = <&csis0_ep>;
+ };
+ };
+ };
+ };
