Boot Tested this patch series against v3.6 tag(applied cleanly) on
panda board and
PM tested(hitting off in Idle and suspend) on omap3630 based beagle board.

Note, I also tested the patches against the current master but only
after rebasing, since the current master includes serial patches from
Felipe Balbi[1].

Did you test flow control after off-mode transitons?

Russell indicated that the context save/restore is not saving important
bits related to HW flow control, so I suspect some more testing,
specifically of flow control after off-mode is needed.

Kevin
The testing done was without any flow control enabled.
So, as the patch set is about fixing the flow control stuff, would
you say that your testing without flow control enabled has much value?
I will try to figure out how to do a hardware flow control testing
and see the status after the off mode.
It's software flow control which isn't properly restored...
