Subject: [PATCH v2 0/4] cn10k DDR Performance monitor support

This patch series adds DDR performance monitor support
on Marvell cn10k series of processor.

First patch adds device tree binding changes.
Second patch add basic support (without overflow and event
ownership). Third and fourth patch adds overflow and event
ownership respectively.

Seems like 4th patch can be merged in second patch,
For easy review it is currently separate
 - DT binding changed to new DT Schema
 - writeq/readq changed to respective relaxed

Bharat Bhushan (4):
  dt-bindings: perf: marvell: cn10k ddr performance monitor
  perf/marvell: CN10k DDR performance monitor support
  perf/marvell: cn10k DDR perfmon event overflow handling
  perf/marvell: cn10k DDR perf event core ownership
