[PATCH 0/9] ARM perf updates for 3.7

Hello,

This patch series contains the ARM perf updates I'd like to push for 3.7
Most of the code is cleanup in preparation for big.LITTLE PMU support,
where we will need to support different types of CPU PMU on the same SoC.

The PMU probing has changed so that we try to identify the PMU using its
DT binding before falling back to probing the current core. The unused
PMU registration mechanism is also removed and platforms registering
the device have been updated accordingly.

Given that this touches a few platforms, I anticipate sending it via
arm-soc.

All feedback welcome,

Will
