These are same as in $ref: "snps,dwmac.yaml#", so do we really need to specify them here?

You use "xxx: true" when you want to accept property from other schema, assuming it is defined there properly. However the snps,dwmac does not define it in specific way because it expects specific implementation to narrow the details. > > Am I missing something here? > >>> + >>> + clocks: >>> + minItems: 1 >>> + maxItems: 4 >> >> Why such flexibility? > > Ok, let me just keep 'maxItems: 4' here for now. > >>> + >>> + clock-names: >>> + minItems: 1 >>> + items: >>> + - const: stmmaceth >>> + - const: pclk >>> + - const: ptp_ref >>> + - const: rgmii >>> + >>> + iommus: >>> + minItems: 1 >>> + maxItems: 2 >> >> Aren't we using only one MMU? > > It was just for future compatibility, but I get your point. > Let me keep the 'maxItems: 1' here for now. > >>> + >>> + mdio: true >>> + >>> + phy-handle: true >>> + >>> + phy-mode: true >>> + >>> + snps,reset-gpio: true >>> + >>> + snps,tso: >>> + $ref: /schemas/types.yaml#/definitions/flag >>> + description: >>> + Enables the TSO feature otherwise it will be managed by MAC HW capability register. >>> + >>> + power-domains: true >>> + >>> + resets: true >>> + >>> + rx-fifo-depth: true >>> + >>> + tx-fifo-depth: true >> >> You do not list all these properties, because you use >> unevaluatedProperties.
