Mode-based sensor drivers are the last option, especially if the sensor has
known registers for configuring the crop size, which seems to me is
possible here?

There's the new common raw sensor model in the works too, which can even
handle separate userspace configuration for analogue and digital crop,
subsampling (INC_ODD/INC_EVEN), binning and output size.

Could you please explore that? Adding hard-coded modes would make this
driver a mess when we move to the new model.

Thanks,
