From f0b55841cc602f9a40f26ce1b0c6ae83c6bfa92f Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 17 Jan 2018 16:46:48 +0800 Subject: [PATCH] ARM: dts: sun9i: Add CCI-400 device nodes for A80 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.
