Subject: [PATCH 2/4] ARM: dts: sun9i: Add CCI-400 device nodes for A80
Date: Tue, 25 Jul 2017 13:09:17 +0800	[thread overview]
Message-ID: <20170725050919.16036-3-wens@csie.org> (raw)
In-Reply-To: <20170725050919.16036-1-wens@csie.org>

The A80 includes an ARM CCI-400 interconnect to support multi-cluster
CPU caches.

Also add the maximum clock frequency for the CPUs, as listed in the
A80 Optimus Board FEX file.
