Subject: [PATCH 7/7] arm64: dts: add dts files for asr Aquilac SoC
From: Qiao Zhou <qiaozhou@...micro.com>
Add initial dtsi file to support ASR Aquilac SoC. It has two clusters.
Cluster0 has 4 * Cortex-A53 and Cluster1 has 4 * Cortex-A73.
Also add dts file to support ASR Aquilac SoC development board which is
based on ASR AquilaC SoC.
