Subject: [PATCH v2 0/6] Marvell Odyssey uncore performance monitor support

This series of patches introduces support for uncore performance monitor
units (PMUs) on the Marvell Odyssey platform. The PMUs covered in this
series include the PEM PMU, LLC-TAD PMU and DDR PMU.

Patches 1, 3 and 5 adds support for PEM pmu, LLC-TAD pmu, DDR pmu
respectively.
Patches 2, 4 and 6 deal with their respective device tree bindings.

v1->v2:
- Changed DT binding file names to match with compatible
- Added missed validations in perf event init
- Fixed Comment style

Gowthami Thiagarajan (6):
  perf/marvell: Marvell PEM performance monitor support
  dt-bindings: perf: Add Marvell PEM performance monitor unit
  perf/marvell : Odyssey LLC-TAD performance monitor support
  dt-bindings: perf: Add Marvell Odyssey LLC-TAD pmu
  perf/marvell: Odyssey DDR Performance monitor support
  dt-bindings: perf: Add Marvell Odyssey DDR PMU
