description: |-
  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
  sensor with square pixel array and 1.58 M effective pixels. This chip
  features a global shutter with variable charge-integration time. It is
  programmable through I2C and 4-wire interfaces. The sensor output is
  available via CSI-2 serial data output (1 Lane).

    description:
      The IMX296 sensor exists in two different models, a colour variant
      (IMX296LQ) and a monochrome variant (IMX296LL). The device exposes the
      model through registers, allowing for auto-detection with a common
      "sony,imx296" compatible string. However, some camera modules disable the
      ability to read the sensor model register, which disables this feature.
      In those cases, the exact model needs to be specified as "sony,imx296ll"
      or "sony,imx296lq".
