Subject: [PATCH v2 0/3] adding vrtc driver for x86/mrst platform

From: Feng Tang <feng.tang@...el.com>

Hi all,

Moorestown platform doesn't have a m146818 RTC device like traditional
x86 PC, but a firmware emulated virtual RTC device(vrtc), which provides
some basic RTC functions like get/set time. vrtc serves as the only
wall clock device on Moorestown platform.

Currently, vrtc init func need be called before xtime's init, thus move
xtime's init into a subsys_initcall: timekeeping_late_init() as suggested
by Thomas

Please review these patches.

Thanks,
Feng

Changelog:
	v2:
	    * add IPC cmd for setting time

---------------
Feng Tang (3):
  timekeeping: moving xtime's init to a later time
  x86: unify current 3 similar ways of saving IRQ info
  x86/mrst: add vrtc driver which serves as a wall clock device
