I've tested your RFC on a few boards that use the .select_pcs() callback,
and didn't find any regressions :)

I have no doubt that the fwnode PCS registration works, however there's no
user of the .fill_available_pcs() path in this series. You may not have access
to HW to test this though, but this is my main concern that we discover issues
when using "internal" PCS with the new API.

I _may_ have time to play around with is on mvpp2, hard to say when though, but
feel free to send another iteration for review :)
