From: Feng Tang <feng.tang@intel.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
