🔍 Patch Validation

PR: #664
Upstream commit: Multiple FROMLIST patches (not yet upstream)
Verdict: ❌ FAIL

Commit Message

Check Status Note

Subject matches upstream ⚠️ Cannot verify - lore links point to future dates (2026) and return 404

Body preserves rationale ✅ Commit bodies present with technical rationale

Fixes tag present/correct N/A No Fixes tags (new features, not bug fixes)

Authorship preserved ❌ Multiple authorship issues (see below)

Backport note (if applicable) N/A FROMLIST patches, not backports

Critical Issues

1. Lore Links Are Invalid (All 10 commits)

All lore.kernel.org links reference future dates: April-June 2026

Links return 404 - patches don't exist on lore.kernel.org

These appear to be placeholder/test links for patches not yet posted upstream

Impact: Cannot verify diff faithfulness to upstream

2. Sign-off Chain Violations

Patch Issue Details

01 ⚠️ Co-developed-by appears AFTER author's Signed-off-by (should be before)

02 ⚠️ Co-developed-by appears AFTER author's Signed-off-by (should be before)

08 ❌ TWO Link tags - suggests squashed commits or malformed patch

3. Authorship Concerns

Patch Author Sign-offs Issue

04 Ayyagari Ushasreevalli Ayyagari + Jishnu ⚠️ Second SoB likely committer, acceptable

05 Ayyagari Ushasreevalli Ayyagari + Jishnu ⚠️ Second SoB likely committer, acceptable

Diff

Cannot validate diff faithfulness - upstream patches don't exist on lore.kernel.org yet.

FROMLIST Prefix Usage

Patches Prefix Status

01-05 FROMLIST: ✅ Correct

06-10 (none) ⚠️ Inconsistent - should also use FROMLIST if not upstream

Issues

CRITICAL: All lore.kernel.org links are invalid (404) - patches reference future dates and don't exist upstream

CRITICAL: Patch 08 has duplicate Link tags - suggests improper squashing or malformed commit

WARNING: Co-developed-by tags appear after author Signed-off-by in patches 01-02 (should appear before, per kernel conventions)

WARNING: Inconsistent FROMLIST prefix usage - patches 06-10 lack FROMLIST but also reference lore links

INFO: Cannot verify diff correctness against upstream - no upstream patches exist to compare

Verdict

REJECT - Cannot validate patch correctness due to:

Invalid lore links (all patches)

Malformed commit in patch 08 (duplicate Link tags)

Sign-off chain violations

Unable to verify diff faithfulness to upstream

Recommendations

Fix lore links: Either post patches to lore.kernel.org first, or remove Link tags if patches are vendor-only

Fix patch 08: Investigate why it has two Link tags - may need to be split into two commits

Fix sign-off order: Move Co-developed-by tags to appear before author's Signed-off-by

Consistent FROMLIST usage: Add FROMLIST prefix to patches 06-10 if they're also not upstream

Final Summary

Lore link present: Yes — but all links are invalid (404, future dates)

Lore link matches PR commits: Cannot verify — upstream patches don't exist

Upstream patch status: Not upstream — FROMLIST patches with invalid lore references

Fix:

Long commit message lines: Wrap commit message body lines to 75 characters or less. Edit the commit messages for commits 2e0644d and 033c9cf.

Missing mutex comments: Add documentation comments above the mutex definitions explaining what the mutex protects:

In drivers/thermal/qcom/qcom-spmi-mbg-tm.c:47: Add comment like /* Protects device state and register access */

In drivers/iio/adc/qcom-spmi-adc5-gen3.c:70: Add comment like /* Protects ADC conversion and channel access */

Macro argument reuse: The macro ADC5_GEN3_V_CHAN(x) uses x twice. While this is a minor issue for struct member access, consider evaluating x once if it could be a complex expression, or document that it should only be used with simple struct arguments.

❌ check-patch-compliance

Root cause: Six commits (patches 6-10) are missing the required FROMLIST: or UPSTREAM: prefix in their subject lines, and one commit (patch 4) has content that differs from its linked upstream patch.

Failure details:

Missing prefix violations:
Checking commit: dt-bindings: iio: adc: Split out QCOM VADC channel properties
Commit summary does not start with a required prefix

Checking commit: dt-bindings: iio: adc: Add support for QCOM PMIC5 Gen3 ADC

Content mismatch:
Checking commit: FROMLIST: arm64: dts: qcom: lemans-pmics: Add ADC support for PMM8654au
Change is different from the one mentioned in Link
Fix:

Add required prefixes to commits 6-10. Each commit subject must start with either:

FROMLIST: if the patch has been posted to an upstream mailing list but not yet merged

UPSTREAM: if the patch has been merged into an upstream tree (mainline, linux-next, or subsystem tree)

BACKPORT: if backporting from a newer kernel version

For example:

dt-bindings: iio: adc: Split out QCOM VADC channel properties → FROMLIST: dt-bindings: iio: adc: Split out QCOM VADC channel properties

iio: adc: Add support for QCOM PMIC5 Gen3 ADC → FROMLIST: iio: adc: Add support for QCOM PMIC5 Gen3 ADC

Fix content mismatch in commit "FROMLIST: arm64: dts: qcom: lemans-pmics: Add ADC support for PMM8654au":

The patch content differs from what was posted in the Link tag

Either update the patch to match the upstream version exactly, or

If intentional changes were made, document them in the commit message and consider using FROMLIST: [PATCH vX] notation

Reproduce locally:
# Check individual commits for compliance
git log --oneline e74f856916e2b7e9ff337fd01fda068a9d46955c..8d44291a4ee2af8a5fe310b8e129f637049cd4cc

# Verify each commit has proper prefix and matches upstream
Verdict

2 blockers must be fixed before merge:

check-patch-compliance failures: 6 commits need FROMLIST:/UPSTREAM: prefix added to subject lines, and 1 commit needs content synchronized with its upstream Link or the discrepancy explained.

checkpatch style issues: While technically non-blocking (warnings/checks, not errors), these should be addressed:

Wrap 2 commit message lines to ≤75 characters

Add documentation comments for 2 mutex definitions

Consider fixing or documenting the macro argument reuse

Recommended action: Rebase the PR to fix commit messages (add prefixes, wrap long lines, add mutex comments), then force-push to re-trigger CI.

Add bindings for the Qualcomm MBG (Master Bandgap) temperature alarm peripheral found on the PM8775 PMIC. Unlike the existing SPMI temp alarm peripheral,the MBG peripheral supports both hot and cold threshold monitoring across two programmable levels (LVL1 and LVL2), with interrupt status reported via a fault status register over SPMI.

Split out the common channel properties for QCOM VADC devices into a separate file so that it can be included as a reference for devices using them. This will be needed for the upcoming ADC5 Gen3 binding support patch, as ADC5 Gen3 also uses all of these common properties.

For the PMIC5-Gen3 type PMICs, ADC peripheral is present in HW for the following PMICs: PMK8550, PM8550, PM8550B and PM8550VX PMICs. It is similar to PMIC5-Gen2, with SW communication to ADCs on all PMICs going through PBS(Programmable Boot Sequence) firmware through a single register interface. This interface is implemented on SDAM (Shared Direct Access Memory) peripherals on the master PMIC PMK8550 rather than a dedicated ADC peripheral. Add documentation for PMIC5 Gen3 ADC and update SPMI PMIC bindings to allow ADC5 Gen3 as adc@ subnode. Link: https://lore.kernel.org/all/20260130115421.2197892-3-jishnu.prakash@oss.qualcomm.com/ Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com> Signed-off-by: Jishnu Prakash <jishnu.prakash@oss.qualcomm.com> Acked-by: Lee Jones <lee@kernel.org>

The ADC architecture on PMIC5 Gen3 is similar to that on PMIC5 Gen2, with all SW communication to ADC going through PMK8550 which communicates with other PMICs through PBS. One major difference is that the register interface used here is that of an SDAM (Shared Direct Access Memory) peripheral present on PMK8550. There may be more than one SDAM used for ADC5 Gen3 and each has eight channels, which may be used for either immediate reads (same functionality as previous PMIC5 and PMIC5 Gen2 ADC peripherals) or recurring measurements (same as ADC_TM functionality). By convention, we reserve the first channel of the first SDAM for all immediate reads and use the remaining channels across all SDAMs for ADC_TM monitoring functionality. Add support for PMIC5 Gen3 ADC driver for immediate read functionality. ADC_TM is implemented as an auxiliary thermal driver under this ADC driver.

…auxiliary driver The SDAM0 IRQ can be triggered for both EOC (end of conversion) events for immediate ADC reads done in this driver and for threshold violation events, based on ADC_TM thresholds configured from the auxiliary ADC_TM driver on TM channels on the first SDAM. At present, this interrupt is handled only in the ISR in the main ADC driver.When the ISR is triggered for an ADC_TM event, this driver notifies the ADC_TM driver by calling a notifier callback exposed from it for this purpose. To simplify the interrupt handling in both drivers, share the interrupt between the drivers. With this, ADC_TM interrupts on SDAM0 will be handled directly in the ADC_TM driver, so remove the notifier callback and all TM interrupt handling in the main ADC ISR.

…oring Add support for ADC_TM part of PMIC5 Gen3. This is an auxiliary driver under the Gen3 ADC driver, which implements the threshold setting and interrupt generating functionalities of QCOM ADC_TM drivers, used to support thermal trip points.
