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.
