Subject: [PATCH 3/4] ARM: dts: sun9i: Add CPUCFG device node for A80 dtsi
Date: Tue, 25 Jul 2017 13:09:18 +0800 [thread overview]
Message-ID: <20170725050919.16036-4-wens@csie.org> (raw)
In-Reply-To: <20170725050919.16036-1-wens@csie.org>
CPUCFG is a collection of registers that are mapped to the SoC's signals
from each individual processor core and associated peripherals, such as
resets for processors, L1/L2 cache and other things.
These registers are used for SMP bringup and CPU hotplugging.
