It turns out that reverting the patch to always power cycle across clock changes fixes things and reverting that patch also doesn't actually cause any known problems (and 150 MHz should even continue to work). Although we really need to get to the bottom of things, it seems expedient to revert while we're waiting for a better solution, hence this series. Also in this series is further increase in the time we'll wait for the DLL to stabilize (found during reboot stress testing) and a fix to the way we handle the card clock being reported as 0 (needed for suspend/resume because of the revert we just did). It's expected that this series could go through Ulf's mmc tree (like the previous) with Kishon's Ack as appropriate.
