Direct usage of rt_clock should be discouraged. For RTC devices the user
cannot choose to follow the host clock with respect to NTP adjustment
and daylight savings changes. For other devices it does not provide
determinism together with -icount or qtest, and it also keeps ticking
while the machine is paused.
This series uses rtc_clock uniformly in device models that provide RTC
functionality, and vm_clock in the omap_lpg whose ticking should be tied
to the VM running state. For consistency I'm also switching the pl031
to rtc_clock; so far it used the vm_clock.
v1->v2: switch omap_lpg to vm_clock
Paolo Bonzini (5):
rtc: add -rtc clock=rt
omap: switch omap_lpg to vm_clock
arm: switch real-time clocks to rtc_clock
pl031: rearm alarm timer upon load
pl031: switch clock base to rtc_clock
