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".
