Subject: [PATCH v2 0/6] media: imx8-isi: Add i.MX952 ISI support
Date: Mon, 31 Aug 2026 11:36:55 +0800	[thread overview]
Message-ID: <20260831-isi_imx952-v2-0-fafdb4b446d4@oss.nxp.com> (raw)

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. Use per-platform format_mask for the output format field to
     match the hardware register width: 6-bit for i.MX8 series,
     7-bit for i.MX8ULP and i.MX9 series.
  3. Remove unused model field from platform data.
  4. Add the i.MX952 compatible string to the DT binding, using
     fallback compatible fsl,imx95-isi.
  5. Add the i.MX952 platform data and of_match entry.
  6. Enable RAW10/12/14 output LSB alignment on platforms that
     support it, removing the RAW16 workaround for i.MX952.
