Sorry I take that back, after trying to figure out which patch breaks PM
I noticed I had some other patches applied also. Looks like PM works just
fine with this series for me, so please feel free to add:

Tested-by: Tony Lindgren <tony@xxxxxxxxxxx>

Note that I have not been able to test this with gpio button as my
boards are in a rack. You may want to do some gpio button tests to
make sure things wake up properly from off idle if you can get hold
of a beagle xm. I posted some instructions how to test earlier today
for Kishon in the "[PATCH v2 00/16] omap_hsmmc: regulator usage
cleanup and fixes" thread.

Tony
