[PATCH v3 0/5] media: imx8-isi: Add i.MX952 ISI support

[Guoniu Zhou]

The series adds support for the i.MX952 Image Sensing Interface (ISI),
which is a minor silicon revision of the i.MX95 ISI.

The i.MX952 ISI reuses the i.MX95 ISI core with the same 8-channel
pipeline and 4 pixel link inputs. The key hardware improvement is the
addition of RAW10/12/14 output LSB alignment, which allows the ISI to
output right-aligned RAW data directly, matching the V4L2 format
requirement without the RAW16 workaround needed on earlier platforms.

The series is organized as follows:

  1. Reorder mxc_imx95_data definition to follow mxc_imx93_data,
     matching the order in the of_match array.
  2. Extend output format mask to 7 bits unconditionally since
     bit 30 is unused on older platforms.
  3. Add the i.MX952 compatible string to the DT binding, using
     fallback compatible fsl,imx95-isi.
  4. Add the i.MX952 platform data and of_match entry.
  5. Enable RAW10/12/14 output LSB alignment on i.MX952, removing
     the RAW16 workaround which no longer works due to the CSI
     formatter providing MSB-aligned data.

Changes in v3:
- [1/5] Add Reviewed-by tag from Laurent
- [2/5] Use unconditional 7-bit mask instead of per-platform approach (Laurent)
- [2/5] Drop Reviewed-by from Frank Li due to significant change and request to review again
- [3/5] Add Reviewed-by/Acked-by tag from Frank, Laurent and Dooley
- [4/5] Extend mask globally instead of per-platform (Laurent)
- [4/5] Add Reviewed-by tag from Frank
- [5/5] Use CHNL_IMG_CTRL_FORMAT_MASK instead of the removed per-platform format_mask (Laurent)
- [5/5] Derive raw_out_lsb from the model field instead of dedicated platform data (Laurent)
- [5/5] Clarify the CHNL_IMG_CTRL_FORMAT_RAW14 comment: the format is documented
  on i.MX{8ULP,91,93,95,952} but only used on i.MX952
- [5/5] Rewrite commit message to explain why the RAW16 workaround fails on i.MX95+ (Laurent)
- [5/5] Add Reviewed-by tag from Frank
- Drop "Remove unused model field" patch; model field is now used to derive
  raw_out_lsb capability (Laurent)
