[PATCH 3/3] arm64: dts: Add dts files for Hisilicon Hi6220 SoC
From: Bintian Wang
Date: Thu Feb 05 2015 - 04:23:52 EST
Add initial dtsi file to support Hisilicon Hi6220 SoC with
support of Octal core CPUs in two clusters and each cluster
has quard Cortex-A53.
We now use the "spin-table" method for SMP, and it will be
changed to PSCI later.
Also add dts file to support HiKey development board which
based on Hi6220 SoC and document the devicetree bindings.
These dts files will be changed later and more nodes will be
added to describe other devices.
