There are no hardware agnostic features here. PHY drivers are pretty
much thin layers which talk to the hardware. Take a look at the C
drivers, what hardware agnostic features do you see in them?

People can easily test this driver, its an easily available USB
dongle, which will work on any USB port, with any SoC architectures.
