Yes typo, Fixed over my branch, sorry for that...
I expect a comment about bps, Bit per Second, used in `bus-speed-bps`
You will add it by your self in property-units.txt, or required my patch?
If your confirm that, ready for: Reviewed-by

If you want to add it, that's fine. But it's really not something that
comes up often. For UARTs, there's already the "current-speed"
property and most other things I can think of use Hz to express
speeds.

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
