From d7dd5fd773497d7b63e7a35fcaa270c9f859432b Mon Sep 17 00:00:00 2001 From: Suzuki K Poulose Date: Tue, 23 Feb 2016 10:49:55 +0000 Subject: arm-cci: CoreLink CCI-550 PMU driver Add ARM CoreLink CCI-550 cache coherent interconnect PMU driver support. The CCI-550 PMU shares all the attributes of CCI-500 PMU, except for an additional master interface (MI-6 - 0xe). CCI-550 requires the same work around as for CCI-500 to write to the PMU counter.
