[PATCH v5 1/2] dt-bindings: power: reset: qcom-pon: Add new compatible PMM8654AU

[Rakesh Kota]

PMM8654AU is a distinct PMIC variant from PMM8650AU despite sharing the
same PMIC subtype. PMM8654AU implements additional registers added to
the "hlos" register address spaces, so add qcom,pmm8654au-pon as a
fallback to qcom,pmk8350-pon to distinguish it from the baseline
PMK8350 PON implementation.

The GEN3 PON peripheral requires two register address spaces: "hlos"
for the primary PON block and "pbs" for the address needs to be
specified to facilitate software debouncing. Set minItems: 2 for reg
in the qcom,pmk8350-pon if/then constraint to enforce that both
address spaces are always present.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:

Pre-existing issues:
- [High] The schema incorrectly forbids `mode-*` properties for `pmk8350-pon` and its fallbacks, breaking reboot mode configuration.

dt-bindings: power: reset: qcom-pon: Add new compatible PMM8654AU

This commit introduces the PMM8654AU compatible string as a fallback to the
baseline PMK8350 PON implementation. It also updates the schema to enforce
that both the hlos and pbs register address spaces are always present for
the Gen3 PON peripherals.

[Severity: High]
This is a pre-existing issue, but does the current schema incorrectly forbid
mode-* properties for pmk8350-pon and its fallbacks, breaking reboot mode
configuration?

Because the Gen3 compatibles are missing from the earlier allOf if condition
that matches pm8916-pon, pms405-pon, and pm8998-pon, they fall into the else
branch:

    else:
      patternProperties:
        "^mode-.*$": false

Will this cause dtbs_check to spuriously reject valid mode-* properties for
the newly added pmm8654au-pon PMIC?
