I love working with drivers that tells me things like "hey you forgot to
add the 'core' clock", rather than having to spend hours bisecting which
register access it is that's causing that reboot and then try to drill
that down to a particular clock.

Apart from that, the "get-all-the-clocks" would work fine as well. Does
this API exist yet?
