Subject: [PATCH v2 3/8] ARM: dts: sun9i: Add CPUCFG device node for A80 dtsi
Date: Thu, 4 Jan 2018 22:37:49 +0800 [thread overview]
Message-ID: <20180104143754.2425-4-wens@csie.org> (raw)
In-Reply-To: <20180104143754.2425-1-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.
