Oops, I forgot to append proper From: author lines in five commits (patch 04/10 to 09/10). Didn't mean to supersede your authoship.
I'd respin the patchset later, waiting for some feedback.
Can you please resend this with this fixed up if you want to get this into 3.8?
Thanks for your kind reminder. Here's v2, providing From: authorship lines in five patches (04 to 08). No logical change in the patches.

V2: provide missing authorship From: lines in five patches (04 to 08)
Here are sh-sci serial driver fixes that have been cooking for months privately on my end:
* rework console PM with the help of serial-core's uart_change_pm()
* provide missing piece in SCIFB support (from Yoshii-san)
* address console write function vs. SMP lockup issue
and so on. Comments and suggestions are welcome.
Build tested with vanilla v3.6, but not boot- nor PM-tested with newer kernels after v3.4. Anyone with can-sleep shmobile systems, please give it try.
Thanks in advance,
