Subject: [PATCH v3 2/8] ARM: dts: sun9i: Add CCI-400 device nodes for A80
Date: Mon, 15 Jan 2018 15:14:44 +0800 [thread overview]
Message-ID: <20180115071450.18355-3-wens@csie.org> (raw)
In-Reply-To: <20180115071450.18355-1-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.
