Yes, there are several MAC bindings that already define a delay property:
Documentation/devicetree/bindings/net/allwinner,sun8i-a83t-emac.yaml:
allwinner,rx-delay-ps:
Documentation/devicetree/bindings/net/allwinner,sun8i-a83t-emac.yaml:
allwinner,rx-delay-ps:
Documentation/devicetree/bindings/net/apm-xgene-enet.txt:- rx-delay:
Delay value for RGMII bridge RX clock.
Documentation/devicetree/bindings/net/apm-xgene-enet.txt: rx-delay
= <2>;
Documentation/devicetree/bindings/net/cavium-pip.txt:- rx-delay: Delay
value for RGMII receive clock. Optional. Disabled if 0.
Documentation/devicetree/bindings/net/mediatek-dwmac.txt:-
mediatek,rx-delay-ps: RX clock delay macro value. Default is 0.
Documentation/devicetree/bindings/net/mediatek-dwmac.txt:
mediatek,rx-delay-ps = <1530>;
standardizing on rx-delay-ps and tx-delay-ps would make sense since that
is the lowest resolution and the property would be correctly named with
an unit in the name.
