[RFC PATCH 0/2] serial 8250 platform PM hooks

[Manuel Lauss]

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

Manuel Lauss (2):
  8250: allow platform uarts to install PM callback.
  Alchemy: UART PM through serial framework.
