OK, as you see I'm a bit "outdated" :-)
What would be the alternative? There is a bunch of vendor-specific PHY
features that I would like to expose at some point (e.g. regulation of
TX voltage levels). Thanks!

TX voltages sound like they are board specific, so use DT properties.

For runtime properties, look at phy tunables.

Ok, but as far as I understand tunables, these need to be "generalized".
I was wondering if there is some interface (sysfs / proc / other) to set
parameters which are very specific to a PHY implementation?

Thanks,
