Subject[PATCH v7 0/2] Add ThunderX2 SoC Performance Monitoring Unit driver
This patchset adds PMU driver for Cavium's ThunderX2 SoC UNCORE devices.
The SoC has PMU support in L3 cache controller (L3C) and in the
DDR4 Memory Controller (DMC).

Incorporated review comments [3].
Modified driver as loadable module.
Updated Documentation with Event description.
Removed per-channel(no SMC calls) sampling implementation(
Since DMC and L3C channels are interleave, we have decided to
sample channel zero and prorate it to account for a Device).


Rebased to 4.18-rc1
Updated with comments from John Garry[3]
