This is a single-patch series (v7) adding a new compatible string for the Qualcomm Glymur SoC's fastrpc binding, declaring it fully compatible with the existing Kaanapali fastrpc. The change is straightforward and follows standard dt-bindings patterns.

**Assessment: Looks good.** This is a well-understood, low-risk dt-bindings change that already has a Reviewed-by from a DT maintainer (Krzysztof Kozlowski).

Claude review: dt-bindings: misc: qcom, fastrpc: Add compatible for Glymur

[Claude Code Review Bot]

Patch Review

**The change:** Converts the `compatible` property schema from a flat `enum` to a `oneOf` with two alternatives:
1. The original enum (`qcom,kaanapali-fastrpc`, `qcom,fastrpc`)
2. A new fallback pattern: `qcom,glymur-fastrpc`, `qcom,kaanapali-fastrpc`

This correctly models that Glymur fastrpc is fully compatible with Kaanapali fastrpc, using the standard DT idiom of `<soc-specific>, <fallback>`.

**Minor observations:**

- The YAML schema change is correct. Using `oneOf` with a separate `items` block for the fallback compatible pair is the standard pattern in dt-bindings.

- The `items` block with a single-entry `enum` (lines 205-206):
  ```yaml
        - items:
            - enum:
                - qcom,glymur-fastrpc
            - const: qcom,kaanapali-fastrpc
  ```
  Using `enum` with a single entry works but `const: qcom,glymur-fastrpc` would be slightly more concise (matching the style used for the kaanapali fallback on the next line). This is a stylistic nit — using `enum` is also acceptable and is the preferred pattern in many bindings since it makes future additions easier without restructuring.

- The commit message is clear and the changelog is thorough.

- Has Reviewed-by from Krzysztof Kozlowski (Qualcomm DT maintainer).

**Verdict:** No issues. Patch is ready to merge.
