Sail Mailbox changes for dt-bindings & Devicetree Overlay

[snegi-qti]

Add lemans-sail-mb.dtso overlay for Lemans platform providing:

ipcc_computeL1: IPCC Compute-L1 controller
sail_mailbox: SAIL Mailbox device node

Also add IPCC_CLIENT_SAIL0/1/2/3 client ID definitions to the qcom-ipcc dt-bindings header.

arch/arm64/boot/dts/qcom/lemans-sail-mb.dtso	✅	New overlay; BSD-3-Clause license; uses SAIL IDs from commit 1

---

Issues

None identified. Both commits are well-formed vendor-only changes with:

• Proper QCLINUX: prefix indicating vendor scope
• Clear commit messages explaining the additions
• Correct authorship and sign-off
• Logical dependency ordering (header definitions before usage)
• Consistent formatting with existing codebase patterns

---

Verdict

Merge as-is. Both patches are correctly structured vendor-only contributions that add SAIL Mailbox support for the Lemans platform. Commit 1 defines the required IPCC client IDs, and commit 2 adds the device tree overlay that uses them. No upstream comparison is needed or expected for QCLINUX: prefixed patches.

❌ check-patch-compliance

Root cause: Both commits use QCLINUX: prefix, which is not allowed for the target branch qcom-6.18.y.

2026-06-03T12:45:33.1860716Z Checking commit: QCLINUX: dt-bindings: mailbox: qcom-ipcc: Add SAIL client IDs
2026-06-03T12:45:33.1875791Z Commit summary does not start with a required prefix

2026-06-03T12:45:33.1939310Z Commit summary does not start with a required prefix

Fix:

The target branch qcom-6.18.y requires commits to use either:

• UPSTREAM: prefix if the patch has been merged into mainline Linux
• FROMLIST: prefix if the patch has been posted to a mailing list but not yet merged

Since these appear to be Qualcomm-specific additions (SAIL client IDs and Lemans platform overlay), you have two options:

1. If these patches exist on a mailing list: Change the prefix from QCLINUX: to FROMLIST: and include a Link: tag pointing to the lore.kernel.org URL of the patch series.

2. If targeting qcom-next instead: Retarget this PR to the qcom-next or qcom-next-staging branch, where QCLINUX: prefix is allowed for downstream-only changes.

Example fix for option 1:

FROMLIST: dt-bindings: mailbox: qcom-ipcc: Add SAIL client IDs

Add IPCC_CLIENT_SAIL0/1/2/3 client ID definitions (27-30) to
the qcom-ipcc dt-bindings header for use by the SAIL Mailbox
device tree overlay.

Reproduce locally:

git clone https://github.com/qualcomm-linux/kernel-checkers.git
cd kernel
bash ../kernel-checkers/check-patch-compliance.sh --kernel-src . --base <base-sha> --head <head-sha>

Verdict

1 blocker to fix: Both commits must be rebased with the correct subject prefix (UPSTREAM: or FROMLIST:) before merging to qcom-6.18.y, or the PR should be retargeted to qcom-next/qcom-next-staging if these are downstream-only changes.
