I wonder what happend to this patch series. I can't seem to find the
patches in mainline, although it's more than 8 months ago when they were
discussed. And I can't see any reason for rejecting them in the thread
either.

I'd like to extend the support to PXA3xx chips and get rid of some board
files in favour of DT. One uncertainty I have about that is clock
handling. What's a good migration path to get those bits moved over?
>From what I can see, when probed solely from the device tree, device
names default to their base address, and the dev_id is a globally
incrementing counter. Are platforms supposed to provide clock aliases in
that form?
