[PATCH v3 10/20] media: i2c: imx219: Infer binning settings from format and crop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Compare the format and crop rectangle dimensions to infer binning
settings, instead of storing the binning mode in the imx219_mode
structure. This removes duplicate information from the mode.
