In the above example, the IMX219 sensor is available at index 0 and IMX477 at index 1. The sensor mode identifier takes the following form:
----
S<Bayer order><Bit-depth>_<Optional packing> : <Resolution list>
----
For the IMX219 in the above example, all modes have a `RGGB` Bayer ordering and provide either 8-bit or 10-bit CSI2 packed readout at the listed resolutions.
For the IMX219 in the above example, all modes have a `RGGB` Bayer ordering and provide either 8-bit or 10-bit CSI2 packed readout at the listed resolutions. The crop is specified as (<x>, <y>)/<Width>x<Height>, where (x, y) is the location of the crop window of size Width x Height in the sensor array. The units remain native sensor pixels, even if the sensor is being used in a binning or skipping mode.
