That's good news! What's your plan on using the indexing the clocks?

I'd rather avoid indexing as that's basically same as the old IRQ
numbering and GPIO numbering schemes that don't work well in the long

We already have quite a few sets of clocks for omaps, so the indexing
is already an issue. My thinking is that indexing should only be used
if the same physical clock has multiple outputs.
