[PATCH] media: Add a driver for the ov5640 sensor.

2015-09-30 Thread Javier Martin 
The ov5640 sensor from Omnivision supports up to 2592x1944
and both CSI and MIPI interfaces.

The following driver adds support for the CSI interface only
and VGA, 720p resolutions at 30fps.

+* Omnivision 1/4-Inch 5Mp CMOS Digital Image Sensor
+
+The Omnivision OV5640 is a 1/4-Inch CMOS active pixel digital image sensor with
+an active array size of 2592H x 1932V. It is programmable through a simple
+two-wire serial interface.
+
+Required Properties:
+- compatible: value should be "ovti,ov5640"
+- clocks: reference to the xclk clock
+- clock-names: should be "xclk"
+- clock-rates: the xclk clock frequency
+
+Optional Properties:
+- reset-gpio: Chip reset GPIO
+- pwdn-gpio: Chip power down GPIO
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+{
+   ...
+
+   ov5640: ov5640@3c {
+   compatible = "ovti,ov5640";
+   pinctrl-names = "default";

Sorry for the unrelated patches,
I will submit this again.
