+Micron 3.1Mp CMOS Digital Image Sensor
+--------------------------------------
+
+The Micron MT9T111 and MT9T112 are 1/4 inch 3.1Mp System-On-A-Chip (SOC) CMOS
+digital image sensors which support up to QXGA (2048x1536) image resolution in
+4/3 format.
+
+The sensors can be programmed through a two-wire serial interface and can
+work both in parallel data output mode as well as in MIPI CSI-2 mode.
+
+Required Properties:
+- compatible: shall be one of the following values
+ "micron,mt9t111" for MT9T111 sensors
+ "micron,mt9t112" for MT9T112 sensors
+
+Optional properties:
+- powerdown-gpios: reference to powerdown input GPIO signal. Pin name "STANDBY".
+ Active level is high.
+
+The device node shall contain one 'port' sub-node with one 'endpoint' child
+node, modeled accordingly to bindings described in:
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+--------
+
+ mt9t112@3d {
+ compatible = "micron,mt9t112";
+ reg = <0x3d>;
+
+ powerdown-gpios = <&gpio4 2 GPIO_ACTIVE_HIGH>;
+
+ port {
+ mt9t112_out: endpoint {
+ pclk-sample = <1>;
+ remote-endpoint = <&ceu_in>;
+ };
+ };
+ };
