No, Pref keep standard and use Hz.

This if finally:
```
SMSC com20020 Arcnet network controller

Required property:
- timeout-ns: Arcnet bus timeout, Idle Time (328000 - 20500)
- bus-speed-bps: Arcnet bus speed (10000000 - 156250)
- smsc,xtal-mhz: External oscillator frequency
- smsc,backplane-enabled: Controller use backplane mode
- reset-gpios: Chip reset pin
- interrupts: Should contain controller interrupt

arcnet@28000000 {
	compatible = "smsc,com20020";

	timeout-ns = <20500>;
	bus-speed-hz = <10000000>;
	smsc,xtal-mhz = <20>;
	smsc,backplane-enabled;

	reset-gpios = <&gpio3 21 GPIO_ACTIVE_LOW>;
	interrupts = <&gpio2 10 GPIO_ACTIVE_LOW>;
};
```
If confirmed, for me is right
