Slighly annoying to have to add a table for each SoC. I'd imagine
this growing quite large.
Would it be possible to query our parent clock name and then append a
"_480m" suffix? Then you can magically get the name you want, right?
That doesn't preclude you from later overriding this or adding a "dts"
property for it, but it means no tables for now and (hopefully) for
the forseeable future. ...and you get to kill a bunch of code in this
patch...
You could fall back to some generic name based on the PHY device tree
node name if you wanted, or use the ID allocator...
Otherwise, this all looks good to me. If you have a good reason why
using the parent name isn't a good idea, let me know and I can add my
Reviewed-by on this patch.
