[v15,04/15] hw/ptimer: Introduce timer policy feature

Message ID d37b6019bf1a0d73db7c0fc2a75b2529e0300332.1469110137.git.digetx@gmail.com (mailing list archive)

Dmitry Osipenko July 21, 2016, 2:31 p.m. UTC
Some of the timer devices may have behaviour different from what ptimer
provides. Introduce ptimer policy feature that allows ptimer users to
change default and wrong timer behaviour, for example to continuously
trigger periodic timer when load value is equal to "0".
