-* Aptina MT9V111 CMOS sensor
-----------------------------
-
-The Aptina MT9V111 is a 1/4-Inch VGA-format digital image sensor with a core
-based on Aptina MT9V011 sensor and an integrated Image Flow Processor (IFP).
-
-The sensor has an active pixel array of 640x480 pixels and can output a number
-of image resolution and formats controllable through a simple two-wires
-interface.
-
-Required properties:
---------------------
-
-- compatible: shall be "aptina,mt9v111".
-- clocks: reference to the system clock input provider.
-
-Optional properties:
---------------------
-
-- enable-gpios: output enable signal, pin name "OE#". Active low.
-- standby-gpios: low power state control signal, pin name "STANDBY".
-  Active high.
-- reset-gpios: chip reset signal, pin name "RESET#". Active low.
-
-The device node must contain one 'port' child node with one 'endpoint' child
-sub-node for its digital output video port, in accordance with the video
-interface bindings defined in:
-Documentation/devicetree/bindings/media/video-interfaces.txt
-
-Example:
---------
-
-        &i2c1 {
-                camera@48 {
-                        compatible = "aptina,mt9v111";
-                        reg = <0x48>;
-
-                        clocks = <&camera_clk>;
