+* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
|
|
+
|
|
+The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
|
|
+an active array size of 3280H x 2464V. It is programmable through I2C
|
|
+interface. The I2C address is fixed to 0x10 as per sensor data sheet.
|
|
+Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
|
|
+data lanes.
|
|
+
|
|
+Required Properties:
|
|
+- compatible: value should be "sony,imx219" for imx219 sensor
|
|
+- reg: I2C bus address of the device
|
|
+- clocks: reference to the xclk input clock.
|
|
+- clock-names: should be "xclk".
|
|
+- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
|
|
+- AVDD-supply: Analog voltage supply, 2.8 volts
|
|
+- DVDD-supply: Digital core voltage supply, 1.2 volts
|
|
+
|
|
+Optional Properties:
|
|
+- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
|
|
+ released after all supplies are applied.
|
|
+ This is an active high signal to the imx219.
|
|
+
|
|
+The imx219 device node should contain one 'port' child node with
|
|
+an 'endpoint' subnode. For further reading on port node refer to
|
|
+Documentation/devicetree/bindings/media/video-interfaces.txt.
|
|
+
|
|
+Endpoint node required properties for CSI-2 connection are:
|
|
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
|
|
+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
|
|
+- data-lanes: should be set to <1 2>, or <1 2 3 4> (two or four lane CSI-2
|
|
+ supported)
|
|
+
|
|
+Example:
|
|
+ sensor@10 {
|
|
+ compatible = "sony,imx219";
|
|
+ reg = <0x10>;
|
|
+ #address-cells = <1>;
|
|
+ #size-cells = <0>;
|
|
+ clocks = <&imx219_clk>;
|
|
+ clock-names = "xclk";
|
|
+ xclr-gpios = <&gpio_sensor 0 0>;
|
|
+ DOVDD-supply = <&vgen4_reg>; /* 1.8v */
|
|
+ AVDD-supply = <&vgen3_reg>; /* 2.8v */
|
|
+ DVDD-supply = <&vgen2_reg>; /* 1.2v */
|
|
+
|
|
+ imx219_clk: camera-clk {
|
|
+ compatible = "fixed-clock";
|
|
+ #clock-cells = <0>;
|
|
+ clock-frequency = <24000000>;
|
|
+ };
|
|
+
|
|
+ port {
|
|
+ sensor_out: endpoint {
|
|
+ remote-endpoint = <&csiss_in>;
|
|
+ clock-lanes = <0>;
|
|
+ data-lanes = <1 2>;
|
|
+ };
|
|
+ };
|
|
+ };
