[GIT PULL] arm-cci PMU updates for 4.1

[GIT PULL] arm-cci PMU updates for 4.1

[Will Deacon]

Hi Olof, Arnd,

Please can you pull the following ARM CCI PMU updates for 4.1? Suzuki
has reworked parts of the existing driver so that it can be used on CPUs
booting in non-secure mode (i.e. ARM64 systems) and also make it easier
to port over to new IP, such as CCI-500.

It's coming via me as $ARM_PERF_GUY, but Nico has Acked the core driver
(non-PMU) changes. Note that these have been in next for a bit, but I
can drop the branch once you've pulled.

Cheers,

Will

CCI-400 PMU updates

This series reworks some of the CCI-400 PMU code so that it can be used
on both ARM and ARM64-based systems, without the need to boot in secure
mode on the latter. This paves the way for CCI-500 support in future.

Gentle ping as I'm off all next week and won't be able to chase this up...

Merged now. The Kconfig merge was a bit messy since someone decided to sort the
file, and Stephen will see that too (cc:d here).

Tested the CCI PMU on the for-next branch, works well. Thanks Olof.
