❌ checkpatch

Root cause: Two vendor-specific DT compatible strings are not documented in vendor-prefixes.yaml.

Failure details:

WARNING: DT compatible string "qcom,eeprom" appears un-documented -- check ./Documentation/devicetree/bindings/
#26: FILE: arch/arm64/boot/dts/qcom/qcs6490-rb3gen2-camera-sensor.dtsi:180:
+		compatible = "qcom,eeprom";

WARNING: DT compatible string "qcom,cam-sensor" appears un-documented -- check ./Documentation/devicetree/bindings/
#64: FILE: arch/arm64/boot/dts/qcom/qcs6490-rb3gen2-camera-sensor.dtsi:218:
+		compatible = "qcom,cam-sensor";

Fix: These are vendor-specific camera subsystem compatible strings. Two options:

1. Add DT binding documentation (recommended for upstream):

   • Create Documentation/devicetree/bindings/media/qcom,eeprom.yaml
   • Create Documentation/devicetree/bindings/media/qcom,cam-sensor.yaml

2. Accept as vendor-only (if not upstreaming):

   • These warnings are acceptable for vendor-only DTS changes
   • The compatible strings are already used elsewhere in the tree

Reproduce locally:

./scripts/checkpatch.pl --strict --ignore FILE_PATH_CHANGES --git dc0f4d4280a7..9c84a020ce63

❌ dtb-check

Root cause: The new camera sensor nodes fail schema validation because qcom,eeprom and qcom,cam-sensor compatible strings have no upstream bindings, and the nodes are missing the required ranges property expected by the parent qcom,cci binding.

Failure details:

qcom,cci0 (qcom,cci): qcom,cam-sensor12: 'ranges' is a required property
qcom,cci0 (qcom,cci): qcom,eeprom1: 'ranges' is a required property
/soc@0/qcom,cci0/qcom,cam-sensor12: failed to match any schema with compatible: ['qcom,cam-sensor']
/soc@0/qcom,cci0/qcom,eeprom1: failed to match any schema with compatible: ['qcom,eeprom']
qcom,cam-sensor12 (qcom,cam-sensor): gpio-req-tbl-label: b'CAMIF_MCLK1^@CAM_RESET1^@CAM_CUSTOM1^@' is not of type 'object', 'integer', 'array', 'boolean', 'null'
qcom,eeprom1 (qcom,eeprom): gpio-req-tbl-label: b'CAMIF_MCLK1^@CAM_RESET1^@CAM_CUSTOM1^@' is not of type 'object', 'integer', 'array', 'boolean', 'null'

Analysis:

1. Missing schema: No binding YAML exists for qcom,eeprom or qcom,cam-sensor — these are vendor-specific camera subsystem nodes
2. Missing ranges property: The parent qcom,cci binding expects child nodes to have a ranges property
3. Property type mismatch: gpio-req-tbl-label is a vendor-specific string array property not recognized by standard schemas

Fix:

These are vendor-specific camera subsystem nodes that do not have upstream bindings. The dtb-check failures are expected for vendor-only DTS additions. Two paths forward:

1. If upstreaming is planned:

   • Add proper DT binding YAML files for qcom,eeprom and qcom,cam-sensor
   • Add ranges; property to both nodes (empty ranges for non-translating bridges)
   • Document all vendor-specific properties (gpio-req-tbl-label, pwm-switch, etc.)

2. If vendor-only (current state):

   • These failures are acceptable — the nodes follow existing patterns in the tree
   • The same compatible strings and properties are used in other camera sensor nodes
   • The hardware will function correctly despite schema validation failures

Reproduce locally:

make -j$(nproc) O=out CHECK_DTBS=y arch/arm64/boot/dts/qcom/qcs5430-fps-camx.dtb
make -j$(nproc) O=out CHECK_DTBS=y arch/arm64/boot/dts/qcom/qcs6490-rb3gen2-vision-mezzanine-camx.dtb

❌ check-patch-compliance

Root cause: The commit uses the QCLINUX: prefix, which is not in the checker's allowed list (FROMLIST:, FROMGIT:, UPSTREAM:, BACKPORT:).

Failure details:

Checking commit: QCLINUX: arm64: dts: qcom: Add IMX577 DTSI changes to Support CAM1
Commit summary does not start with a required prefix

Analysis:

This is a known checker limitation for vendor-only commits. The check-patch-compliance checker only accepts upstream-linkable prefixes:

• FROMLIST: — posted to mailing list
• FROMGIT: — in a maintainer tree
• UPSTREAM: — merged into mainline
• BACKPORT: — backported with modifications

The QCLINUX: prefix is used for vendor-only changes with no upstream equivalent, but the checker does not recognize it.

Fix:

No action required. This is a vendor-only DTS change for Qualcomm camera subsystem support. The QCLINUX: prefix is correct and intentional. The checker failure is expected and acceptable for vendor-only commits.

If this were to be upstreamed in the future:

1. Post the patch to the devicetree mailing list
2. Change prefix to FROMLIST:
3. Add Link: <lore-url> to the commit message

---

Verdict

3 blockers to address before merge:

1. checkpatch warnings — Acceptable as vendor-only; or add DT bindings if upstreaming
2. dtb-check failures — Expected for vendor-specific camera nodes without upstream bindings; acceptable as-is
3. check-patch-compliance failure — Known limitation; QCLINUX: prefix is correct for vendor-only changes

Recommendation: The failures are all related to vendor-specific camera subsystem nodes that lack upstream DT bindings. If this is a vendor-only change (not intended for upstream), all failures are acceptable and the PR can merge as-is. If upstreaming is planned, DT binding YAML files must be added first.
