arm-cci: Add CCI-500 PMU support CCI-500 provides 8 event counters which can count any of the supported events independently. The PMU event id is a 9-bit value made of two parts. bits [8:5] - Source port 0x0-0x6 Slave Ports 0x8-0xD Master Ports 0xf Global Events to CCI 0x7,0xe Reserved bits [0:4] - Event code (specific to each type of port) The generic CCI-500 controlling interface remains the same with CCI-400. However there are some differences in the PMU event counters. - No cycle counter - Upto 8 counters(4 in CCI-400) - Each counter area is 64K(4K in CCI400) - The counter0 starts at offset 0x10000 from the base of CCI Cc: Punit Agrawal <punit.agrawal@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: devicetree@vger.kernel.org Signed-off-by: Suzuki K.
