This patch fixes the usecount tracking for omap3+, previously the usecount numbers were rather bogus and were not really useful for any purpose. Now usecount numbers track the number of really active clients on each domain. This patch also adds support for usecount tracking on powerdomain level and autoidle flag for clocks that are hardware controlled and should be skipped in usecount calculations.

I was a little skeptical about this when I first saw it. But I am sure you would have thought through :) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
