[PATCH 0/2] perf: marvell: Add CN20K DDR PMU support

[Geetha sowjanya]

This series adds support for the Marvell CN20K DRAM Subsystem (DSS)
performance monitor in the existing marvell_cn10k_ddr_pmu driver, and
documents the device tree binding for the new compatible string.

The CN20K PMU provides eight programmable counters and two fixed
counters (DDR reads and writes).  Patch 1 adds the devicetree schema for
"marvell,cn20k-ddr-pmu".  Patch 2 wires OF and ACPI (MRVL000B) match
entries, adds CN20K register offsets and event maps, and refactors
platform data to use silicon variant flags.
