description: |-
  The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with Square
  Pixel, available in either mono or colour variants. It is programmable
  through I2C and 4-wire interfaces.

  The sensor output is available via CMOS logic parallel SDR output, Low voltage
  LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the default.
  No bindings have been defined for the other busses.

  imx290lqr is the full model identifier for the colour variant. "sony,imx290"
  is treated the same as this as it was the original compatible string.
  imx290llr is the mono version of the sensor.
