A bunch of patches starting to make musb play
well with several different glue layers. There's still
a bunch of stuff to be done, but I figured it was too
much and it's better testing what we have now then break
the whole thing.
I tested the patches on pandaboard with g_zero and it's
all working fine. I also compile tested all glue layers
(but blackfin ones, due missing compilers on my machine)
to be sure I'm not breaking compilation.
I've looked at the patches and have been puzzled by this claim about
compile testing all glue layers -- there's a lot of compilation errors that
must be generated by the patchset as published. Maybe you've fixed it up
afterwards, I don't know.
These patches have also been applied to linux-omap for
testing. I hope we still have time to add these to mainline
as they make lots of things a lot simpler to handle.
With these patches we will be able to implement pm_runtime
for OMAP without breaking Davinci or Blackfin, for example.
There's also no more magic to support blackfin as musb_core
doesn't care about clocks, it's all handled by glue layer.
Let me know if you can still apply these, I hope you can.

Greg, don't pull this yet -- the patchset still has a lot of issues,
including compilation errors.
WBR, Sergei
