Did you have any luck getting to the bottom of this?

I am still waiting for feedback from design. They were trying to confirm
my observations. Unfortunately, it is taking some time. I will ping them
again.

Ok, thanks. If pinging doesn't work, bribery can be quite effective with
hardware guys :)

Yes looks like I am going to need to get creative :-)

It would be good to take your PMU suspend/resume patches once we know that
they will get used.

Yes that would be good. I could drop the 4460 specific changes for now
and make 4460 work in the same way as 4430 (using CTI) for the time
being and see if we can get these in. However, I recall that was not
working for you, but it was working fine for me.

Indeed, that hack didn't help me and I'd rather not commit it if it only
partially fixes the problem. A better bet might just be to go with your
original approach and see how many bug reports we receive. That might also
help us narrow down the problem, but it's your call.

Ok, I think that that is best.

In the meantime, I pushed what I think is the latest drop of your series to
a new branch on kernel.org:

  git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git perf/omap4-dev

Looks good.

I just wanted to let you know that I have been updating the PMU patches
for OMAP. Latest can be found here [1]. I have not included Paul's patch
[2] in this series at the moment, because although it works well for
OMAP4, I need to create the HWMOD structures for OMAP3. Without these
structures it breaks OMAP3 PMU support. Once this is done we should be
able to get rid for the OMAP3 dependency on ETM. Unfortunately, Benoit
(Mr HWMOD) is out on his holidays but should be back next week and then
maybe he can give me some guidance on this HWMOD stuff.

Cheers
Jon
