[PATCH v3 06/14] media: rkisp1: Add and set registers for crop for i.MX8MP
From: Paul Elder
Date: Fri Nov 18 2022 - 04:40:42 EST
The ISP version in the i.MX8MP has a separate set of registers for crop
that is currently not handled. Add a feature flag to determine which
type of crop the ISP supports and set the crop registers based on that.

Changes since v2:
- Document the RKISP1_FEATURE_DUAL_CROP and RKISP1_FEATURE_RSZ_CROP bits
- Use the rkisp1_has_feature() macro
