+1 - not experimental please.

While I agree with Mike and Paul that there is room for a lot of 
improvements to the clock APIs, I think the existing APIs in this patch 
series can become macro wrappers around any new APIs improvements we add 
in the future.

We should have really done that for the 
clk_prepare_enable/unprepare_disable(), but it should certainly be 
doable for future API additions now that we have the atomic/non-atomic 
differentiation out of the way.

Thanks,
