Hi Maxime,

The problem it is specific to our soc, so is it possible to

propose "optional clock" for 2 extras clocks in snps,dwmac.yaml

and "official" description in soc yaml file (stm32-dwmac.yaml) ?

  clocks:
    minItems: 1
    maxItems: 5
    additionalItems: true
    items:
      - description: GMAC main clock
      - description: Peripheral registers interface clock
      - description:
          PTP reference clock. This clock is used for programming the
          Timestamp Addend Register. If not passed then the system
          clock will be used and this is fine on some platforms.

+      - description: optional clock

+      - description: optional clock

Thanks

Christophe
