Then the branch was PM-tested to determine whether it can suspend and 
serial-resume properly, and whether dynamic idle works.  These tests 
didn't go so well:

- 3530ES3 Beagleboard here was able to enter retention-idle
  suspend, and leave it with serial wakeup, but the CORE powerdomain never 
  entered a low-power state.  Dynamic retention-idle with serial wakeup
  never resumed, and the test stopped there:

- 37xx EVM and 3730 Beagle XM fared better; they made it through the whole 
  test program, but the CORE powerdomain also never entered a low-power
  state:

Thanks to debugging work by some TI LDC engineers, these two issues have 
been resolved.  Some clockdomain associations had been removed that were 
necessary for the OMAP power management code to function correctly.  The 
obvious ones have been restored to the clock data, and the branch updated.
That's good news. Does that mean we should try to merge these patches
for v3.7 then? Or do we still have issues remaining?

Tony
