Hi Marek

Common PHYs are not the only user of this. Ethernet PHYs can also use
it, as well as SERDESes embedded within Ethernet switches.

That is why i suggested these properties go into something like
serdes.yaml. That can then be included into Common PHY, Ethernet PHYs,
switch drivers etc.

Please could you make such a split?
