The following 2 patches implement a PM hook for platform 8250 UARTs and a sample PM implementation for a MIPS SoC.
Patch #1 hooks a new .pm callback in struct plat_serial8250_port to the rest of serial_core's PM infrastructure,
Patch #2 implements uart power gating for Alchemy line of mips socs using the new hook.
With these 2 patches serial console on my test system survives suspend/resume cycles without having to resort to platform-specific hacks in the PM code.
Thanks, Manuel Lauss
