Thank you Andrew. I know little of DSA, but at first sight it appears to
be a _very_ complicated beast for a switch PHY which only
needs a few static register settings applied to it on startup, and has
no further Linux interaction? That's how we use the part, anyway.
Not sure what its typical use case would be.

Woojung and Tristam, what do you think ?
