Seeing the clock changes/cleanups, I gave this a spin on OMAP3
(3530/Beagle, 3530/Overo, 3730/Beagle-xM, 3730/OveroSTORM) to see if it
fixed up the problem where CORE does not hit retention in idle when USB
host is enabled, even with no devices attached.
Unfortunately, it didn't help. :(
Felipe, Keshava, any plans to address this problem which has been around
for a couple cycles now and led me to disable USB host in
omap2plus_defconfig?[1]
