Series [v3,01/14] dt-bindings: media: rkisp1: Add i.MX8MP ISP to compatible | expand

Commit Message

Paul Elder Nov. 18, 2022, 9:39 a.m. UTC 
The ISP that is integrated in the i.MX8MP supports cropping, which
results in a different RSZ_CTRL register layout compared to the RK3399.
Add new definitions for these bits, and use them when the
RKISP1_FEATURE_RSZ_CROP feature is set.

Signed-off-by: Paul Elder <paul.elder@ideasonboard.com>

Changes since v2:

- Condition on RKISP1_FEATURE_RSZ_CROP feature
- Rename bits
- Use the rkisp1_has_feature() macro
