Quoting Vinod Polimera (2022-03-03 03:42:59)
- Some DPU versions support inline rot90. It is supported only for
limited amount of UBWC formats.
- There are two versions of inline rotators, v1 (present on sm8250 and
sm7250) and v2 (sc7280). These versions differ in the list of supported formats and in the scaler possibilities.
Changes in RFC:
- Rebase changes to the latest code base.
- Append rotation config variables with v2 and
remove unused variables.(Dmitry)
- Move pixel_ext setup separately from scaler3 config.(Dmitry)
- Add 270 degree rotation to supported rotation list.(Dmitry)
Changes in V2:
- Remove unused macros and fix indentation.
- Add check if 90 rotation is supported and add supported rotations to rot_cfg.
