these 3 are in Benoit's pm-wip/hwmods-omap4 branch

this is in pm-fixes

ok, but needs respin

This is a mess to track manually,  It *really* would be nice if you could
share this on a git tree, or demonstrate how to reproduce this using
public git trees.

For example, I created a working baseline to apply this using

git checkout -b tmp/sr-v2 pm-opp
git merge pm-cpufreq
git merge pm-fixes
git merge benoit/pm-wip/hwmods-omap4 (minor conflict to resolve)
