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

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