19 +* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
21 +The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
22 +an active array size of 3280H x 2464V. It is programmable through I2C
23 +interface. The I2C address is fixed to 0x10 as per sensor data sheet.
24 +Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
28 +- compatible: value should be "sony,imx219" for imx219 sensor
29 +- reg: I2C bus address of the device
30 +- clocks: reference to the xclk input clock.
31 +- clock-names: should be "xclk".
32 +- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
33 +- AVDD-supply: Analog voltage supply, 2.8 volts
34 +- DVDD-supply: Digital core voltage supply, 1.2 volts
37 +- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
38 + released after all supplies are applied.
39 + This is an active high signal to the imx219.
41 +The imx219 device node should contain one 'port' child node with
42 +an 'endpoint' subnode. For further reading on port node refer to
43 +Documentation/devicetree/bindings/media/video-interfaces.txt.
45 +Endpoint node required properties for CSI-2 connection are:
46 +- remote-endpoint: a phandle to the bus receiver's endpoint node.
47 +- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
48 +- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
