Maybe I missed some earlier discussion on this, but why drivers/bus?
I called the davinci stuff 'bus' initially because it piggy-backed the
platform_bus, but now that we have pm_domains, it's using that, and is
unrelated the bus.
Therefore, as with davinci, I suspect this belongs in mach-keystone.

Dead email address (as you know) ;) You can just leave off the email,
or use khilman at kernel.org as one that shouldn't change.
