Cover letter [PATCH 00/10] serial: sh-sci fixes - console PM, SCIFB, SMP lockup, etc.
Hi Paul and serial forks,
Here are sh-sci serial driver fixes that have been cooking for months privately on my end:
* console PM rework 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,
