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

v7->v8:
 - Fixed warning when W=1 and CONFIG_OF=n
 - Rebased to fix merge error

v6->v7:
 - Moved Kconfig to last patch
 - added Reviewed-by

v5->v6:
 - Changed COMPILE_TEST to (COMPILE_TEST && 64BIT)

v4->v5:
 - Added missing COMPILE_TEST dependency

v3->v4:
 - Added Rob Herring reviewed-by for dt-binding patch

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.

v1->v2:
 - DT binding changed to new DT Schema
 - writeq/readq changed to respective relaxed
 - Using PMU_EVENT_ATTR_ID

  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
