From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Thu, 4 Jan 2018 22:37:48 +0800 Subject: [PATCH v2 2/8] ARM: dts: sun9i: Add CCI-400 device nodes for A80 In-Reply-To: <20180104143754.2425-1-wens@csie.org> References: <20180104143754.2425-1-wens@csie.org> Message-ID: <20180104143754.2425-3-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.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.
