While testing, I found out this patch breaks suspend/resume and idle on
at least 34xx.

A first suspend/resume works fine, but on subsequent ones SGX
powerdomain does not hit retention (and thus CORE powerdomain does not

Simply adding back the above 5 lines (the SGX ones) gets things working
again, which suggests something isn't quite right with SGX, but I
haven't found the exact reason yet.

Thanks for the report, I will take a look.

Kevin and I did some debugging on this.  It turns out that there is a bug 
in the recent clockdomain abstraction code in the git.pwsan.com 
integration branch that caused the underlying problem.  Will follow up 
with comments on the threads of the original patches.

Kevin is planning to keep the patch under discussion in this thread in 
his 2.6.39 queue...
