13description: |-
14  The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
15  sensor with square pixel array and 1.58 M effective pixels. This chip
16  features a global shutter with variable charge-integration time. It is
17  programmable through I2C and 4-wire interfaces. The sensor output is
18  available via CSI-2 serial data output (1 Lane).

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