Hi Krzysztof, 

snps,dwmac.yaml has defined the reg/interrupt/interrupt-names nodes,
and the JH7110 SoC is also applicable.
Maybe just add reg/interrupt/interrupt-names to the required ?


  required:
    - compatible
+   - reg
    - clocks
    - clock-names
+   - interrupts
+   - interrupt-names
    - resets
    - reset-names

Best regards,
Samin
