NXP i.MX93 family almost reuse ISI IP from i.MX8M family, so add
it support in current ISI driver
Changes in version 5:
- Add back some header files removed in version 4
- Refine some comments placement to make code more clearly
Changes in version 4:
- Update commit message to explain why need to move gasket ops to a structure
- Remove some redundant and unused header files
- Move gasket ops structure variable to imx8-isi-gasket.c and export them by extern
- Drop some check
Changes in version 3:
- Split [PATCH v2 2/2] into two patches, one create a separate file to
store gasket operation and the other to add ISI support for i.MX93.
- Drop some debug message in gasket operation.
- Merge .gasket_enable and .gasket_config to .gasket_enable
- Drop some dead code
- Some other small updates
Changes in version 2:
- Remove two patches which used to rename imx8 to imx.
[PATCH 1/4] media: dt-bindings: media: rename nxp,imx8-isi.yaml to nxp,imx-isi.yaml
[PATCH 2/4] media: nxp: rename imx8-isi to imx-isi and remove reference to i.MX8
- Modify commit log to more accurately match its goal.
- Remove redundant "media" in patch subject.

MIPI-CSI2 or parallel interface? Yes, it's Media Mix Domain Block Control(I name it Disp_Mix due to history reason). I check RM in NXP Website and don't found 0x30 as you said since it's REV2, not latest one which still under review.
