Merge tag 'arm-perf-3.13' of git://git./linux/kernel/git/will/linux into next/drivers

From Will Deacon:
Addition of an ARM PMU driver for the CCI-400 coherent interconnect
found on big.LITTLE systems, such as TC2.

This was originally sent for 3.12, but the device-tree bindings hadn't
settled down so here's the improved version for 3.13. I think the code
has benefited from the wait.

* tag 'arm-perf-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
  drivers: CCI: fix the error handle in cci_pmu_probe()
  drivers: CCI: add ARM CCI PMU support
  ARM: dts: Document the CCI PMU DT bindings
  ARM: dts: Improve CCI bindings documentation
