Got a dtbs_check issue in the patchwork CI:

  +arch/riscv/boot/dts/starfive/jh7110-milkv-mars.dtb: gmac1-rgmii-rxin-clock: 'clock-frequency' is a required property
  +	from schema $id: http://devicetree.org/schemas/clock/fixed-clock.yaml#
  +arch/riscv/boot/dts/starfive/jh7110-milkv-mars.dtb: gmac1-rmii-refin-clock: 'clock-frequency' is a required property
  +	from schema $id: http://devicetree.org/schemas/clock/fixed-clock.yaml#

Can you fix that please? Also, I applied some patches the other day that
seem to conflict quite a bit with the common board dts patch. Would you
please do a rebase on top of that please?

Cheers,
Conor.
