Subject: [PATCH 1/6] ARM: prima2: Register with kernel restart handler
Date: Tue, 15 Oct 2019 16:51:42 +0200 [thread overview]
Message-ID: <20191015145147.1106247-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20191015145147.1106247-1-thierry.reding@gmail.com>
From: Guenter Roeck <linux@roeck-us•net>
Register with kernel restart handler instead of setting arm_pm_restart
directly. By doing this, the prima2 reset handler can be prioritized
among other restart methods available on a particular board.
Select a high priority of 192 since the original code overwrites the
default arm restart handler.
