[PATCH 4/4] arm: dts: sun8i: a83t: Set timer node to use phy timer

From: Mylène Josserand <hidden>
Date: 2017-12-11 07:50:56
Also in: linux-devicetree, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

By default, virtual timers are used. These timers need an offset
that must be set by firmware, for example. In case of SMP support,
after a reset, this offset is in "unknown" state and produced
a hang of the kernel.

Use "arm,cpu-registers-not-fw-configured" property allows to use
physical timers instead of virtual ones.
