Re: [PATCH 1/6] dt-bindings: rtc: abx80x: document ABX81X RTCs

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] The newly added SPI compatible strings `abracon,ab0815` and `abracon,ab1815` were omitted from the `if-then` conditional block that restricts trickle charger properties.
- [Low] The schema explicitly introduces SPI support but fails to reference the standard SPI peripheral properties schema, causing common SPI properties to be rejected.

dt-bindings: rtc: abx80x: document ABX81X RTCs

Abracon AB0815 and AB1815 are RTC modules with SPI interface.

[Severity: Low]
Will the schema validator reject standard trickle charger properties for the
newly added AB0815 and AB1815 compatible strings?

Looking at the conditional block later in the file:

allOf:
  - $ref: rtc.yaml#
  - if:
      properties:
        compatible:
          not:
            contains:
              enum:
                - abracon,abx80x
                - abracon,ab0804
                - abracon,ab1804
                - abracon,ab0805
                - abracon,ab1805

Because abracon,ab0815 and abracon,ab1815 were omitted from this enum list,
abracon,tc-diode and abracon,tc-resistor will evaluate to false for these
variants. Should they be added to the list?

[Severity: Low]
Does this binding need to reference the standard SPI peripheral properties?

Because the schema adds SPI support and specifies unevaluatedProperties: false,
standard SPI properties like spi-max-frequency will be rejected by the
validator.

Could a reference to /schemas/spi/spi-peripheral-props.yaml# be added to the
allOf block to permit these common SPI properties?
