I'd love to find an effective way to get more of the msm support
cleaned up (as necessary) and into the mainline.  We're bringing our
work forward and rebasing to keep tracking the latest released kernel,
and working on getting core bits we need that other stuff depends on
in -- look at the thread on linux-pm where the wakelock/suspendblocker
framework has been reviewed, revised, resent repeatedly, etc.

The msm7k unfortunately requires a lot of infrastructure to work given
that the baseband (a black box to us) controls much of the world.
Last time around when I tried submitting some of the core ipc support
to talk to it on the lakml, there seemed to be uncertainty about who
even would review that.

We've definitely dropped the ball as far as interacting with folks on
the lakml on this, but I do wonder if there's a better option than
"delete it all."

We have full support for MSM7201A, including fully functional power
management, working on a number of commercially shipping devices that
we'd absolutely love to get into mainline.  Rebasing and bringing this
stuff forward all the time is a lot of work and certainly not the
optimal way to do it.  Getting it in a couple pieces at a time is slow
going, but it seemed to cause frustration with just the small number
of things we were looking for review/approval for...
