From 5580ea4576b60a4fa615c85e254fab1401149b45 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Mon, 24 Oct 2016 16:26:52 +0100 Subject: hw/ptimer: Add "no counter round down" policy For most of the timers counter starts to decrement after first period expires. Due to rounding down performed by the ptimer_get_count, it returns counter - 1 for the running timer, so that for the ptimer user it looks like counter gets decremented immediately after running the timer. Add "no counter round down" policy that provides correct behaviour for those timers.
