  25 +* Sony IMX290 1/2.8-Inch CMOS Image Sensor
  26 +
  27 +The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
  28 +Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
  29 +interfaces. The sensor output is available via CMOS logic parallel SDR output,
  30 +Low voltage LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the
  31 +default. No bindings have been defined for the other busses.
  32 +
  33 +Required Properties:
  34 +- compatible: Should be "sony,imx290"
  35 +- reg: I2C bus address of the device
  36 +- clocks: Reference to the xclk clock.
  37 +- clock-names: Should be "xclk".
  38 +- clock-frequency: Frequency of the xclk clock in Hz.
  39 +- vdddo-supply: Sensor digital IO regulator.
  40 +- vdda-supply: Sensor analog regulator.
  41 +- vddd-supply: Sensor digital core regulator.
  42 +
  43 +Optional Properties:
  44 +- reset-gpios: Sensor reset GPIO
  45 +
  46 +The imx290 device node should contain one 'port' child node with
  47 +an 'endpoint' subnode. For further reading on port node refer to
  48 +Documentation/devicetree/bindings/media/video-interfaces.txt.
  49 +
  50 +Required Properties on endpoint:
  51 +- data-lanes: check ../video-interfaces.txt
  52 +- link-frequencies: check ../video-interfaces.txt
  53 +- remote-endpoint: check ../video-interfaces.txt
