During configure() we update the ScalerCropMaximum to the correct value for this camera mode and work out the minimum crop size allowed by the ISP. Whenever a new ScalerCrop request is received we check it's valid and apply it to the ISP V4L2 device. When the IPA returns its metadata to us we add the ScalerCrop information, rescaled to sensor native pixels.
