Subject: [PATCH 3/4] ARM: dts: sun9i: Add enable-method for SMP support for the A80 SoC
Date: Thu, 8 Mar 2018 23:00:11 +0800 [thread overview]
Message-ID: <20180308150012.19045-4-wens@csie.org> (raw)
In-Reply-To: <20180308150012.19045-1-wens@csie.org>
Using the enable-method property for SMP support would allow future PSCI
implementations to override any in-OS support. This is better than just
matching against the machine compatible, and then having to determine
whether other methods are available or not.
This adds enable-method properties to all CPU nodes.
