[PATCH 3/4] ARM: dts: sun9i: Add CPUCFG device node for A80 dtsi

From: Chen-Yu Tsai
Date: Tue Jul 25 2017 - 01:16:39 EST


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.
