dt-bindings: rtc: pcf2127: Reference spi-peripheral-props.yaml

From: Fabio Estevam <[email protected]>

Currently, when the 'spi-max-frequency' property is passed, the following dt-schema warning is seen:

'spi-max-frequency' does not match any of the regexes: 'pinctrl-[0-9]+'

Fix it by adding a reference to spi-peripheral-props.yaml and change it to use 'unevaluatedProperties: false'.

2.34.1

Is this real or imaginary error? If imaginary, then do not include it because it just confuses.

Otherwise: which Makefile target in upstream has this error?

You wrote 7 lines for something as simple as saying this is a SPI device thus its binding should reference SPI device properties. Please write concise and accurate commit msgs.

Best regards,
Krzysztof
