[PATCH 01/17] dt-bindings: phy: qcom,edp-phy: Document Nord eDP PHY

[sashiko-bot at kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The new compatible string 'qcom,nord-dp-phy' is omitted from the 'allOf' conditional block that enforces the 3-clock constraint, causing it to fall back to the incorrect 2-clock constraint.

This commit adds the compatible string for the eDP PHY found on the
Qualcomm Nord SoC.

[Severity: Medium]
Will this compatible string incorrectly fall back to the 2-clock constraint?

Looking at the allOf block later in this file, recent hardware generations
requiring 3 clocks are explicitly enumerated:

allOf:
  - if:
      properties:
        compatible:
          enum:
            - qcom,glymur-dp-phy
            - qcom,sa8775p-edp-phy
            - qcom,x1e80100-dp-phy
    then:
      properties:
        clocks:
          minItems: 3
          maxItems: 3
    else:
      properties:
        clocks:
          minItems: 2
          maxItems: 2

Since the Nord PHY utilizes a 38.4 MHz CXO reference clock, should
qcom,nord-dp-phy be added to the enum in the allOf conditional block?

Without it, device trees providing the necessary 3 clocks (aux, cfg_ahb, ref)
might fail schema validation, while incomplete ones providing only 2 clocks
could silently pass via the else fallback.
