This patch adds support for ahb, ipg and per clock, which is needed to support
imx53.
I would also suggest using a more elaborate wording here, some people
might also be interested what are the different clocks for (like,
interface, peripheral, etc etc).
Will do in V2.

I suppose the clock names are also being added/changed in the platform
code in another patchset that's also being queued? What's the target
merge window (if there's a dependency)?
Yes we have more branches to be published next. One of them is
adding the usb device tree nodes and clock entries for mx53.

Thanks,
Michael
