Subject: [PATCH 4/4] arm: dts: sun8i: a83t: Set timer node to use phy timer
Date: Mon, 11 Dec 2017 08:50:01 +0100 [thread overview]
Message-ID: <20171211075001.6100-5-mylene.josserand@free-electrons.com> (raw)
In-Reply-To: <20171211075001.6100-1-mylene.josserand@free-electrons.com>
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.
