[Bharat Bhushan]

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.

v2->v3:
 - dt-binding, ddrcpmu@1 -> pmu@87e1c0000000
 - Add COMPILE_TEST as a dependency
 - Switch to sysfs_emit()
 - Error propagation when invalif event requested
 - Switch to devm_platform_get_and_ioremap_resource()
 - Other review comments on v2.

 - DT binding changed to new DT Schema
 - writeq/readq changed to respective relaxed
