QEMU currently supports lost tick compensation for the periodic RTC

periodic timer with compensation qualities is approaching: KVM's
in-kernel PIT.
A previous discussion [1] showed that we need to introduce per device
control. And we likely also want a global default. Both features require
a generic standardized way to specify the compensation mode.
So this series lays the ground for that by adding a qdev property type
to select from four possible lost tick compensation policies (see patch
1 one for details). And this new property is then applied on the RTC
device.

Applied. Thanks.
