-SMIA/SMIA++ sensor
-
-SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
-defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension
-of that. These definitions are valid for both types of sensors.
-
-More detailed documentation can be found in
-Documentation/devicetree/bindings/media/video-interfaces.txt .
-
-The device node should contain a "port" node which may contain one or more
-endpoint nodes, in accordance with video interface bindings defined in
-Documentation/devicetree/bindings/media/video-interfaces.txt .
-
-Mandatory properties
---------------------
-
-- compatible: "nokia,smia"
-- reg: I2C address (0x10, or an alternative address)
-- clocks: External clock to the sensor
-- clock-frequency: Frequency of the external clock to the sensor
-
-
-Optional properties
--------------------
-
-- reset-gpios: XSHUTDOWN GPIO
-- flash-leds: See ../video-interfaces.txt
-- lens-focus: See ../video-interfaces.txt
-- rotation: Integer property; valid values are 0 (sensor mounted upright)
-	    and 180 (sensor mounted upside down). See
-	    ../video-interfaces.txt .
-- vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor
-  dependent).
-
-
-Endpoint node mandatory properties
-----------------------------------
-
-- data-lanes: <1..n>
-- link-frequencies: List of allowed data link frequencies. An array of
-  64-bit elements.
-
-
-Example
--------
-
-&i2c2 {
-	clock-frequency = <400000>;
-
-	camera-sensor@10 {
-		compatible = "nokia,smia";
-		reg = <0x10>;
-		reset-gpios = <&gpio3 20 0>;
-		vana-supply = <&vaux3>;
-		clocks = <&omap3_isp 0>;
-		clock-frequency = <9600000>;
-		port {
-			smiapp_ep: endpoint {
-				data-lanes = <1 2>;
-				remote-endpoint = <&csi2a_ep>;
-				link-frequencies =
-					/bits/ 64 <199200000 210000000
-						   499200000>;
