+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).
+
+properties:
+ compatible:
+ enum:
+ - sony,imx296
+ - sony,imx296ll
+ - sony,imx296lq
+ 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".
