This series adds the driver for CCI-550 PMU. CCI-550 PMU shares most of the attributes (i.e, counters, event code format, event codes, PMU register file) with that of CCI-500, except for an additional master interface support (MI6). So, we share most of the CCI-500 PMU bits except for a CCI-550 specific event validation.
Patch 1 : Renames the shared bits of CCI-500 PMU defintions to CCI5xx, including the Kconfig symbol, which will support both the PMUs.
Patch 2 : Adds the CCI550_PMU driver
Tested on fast model and an FPGA model.
This series is based on : 4.4-rc1 + [1] + [2] and is also available at : git://linux-arm.org/linux-skp.git cci-updates/4.4-rc1
