[PATCH 0/2] arm_pmuv3: Add support for Samsung Mongoose PMU

[Markuss Broks]

Hello,

This series adds support to performance monitoring unit of
the Samsung Mongoose CPU cores. They were released between
2016 and 2020, and they were used in Samsung Exynos SoCs,
such as Exynos 8890, 8895, 9810, 9820 and 990 (9830).
They implement ARMv8.2-A ISA and they are used as a fast
cluster (big in the big.little scheme).

This series consists of a patch adding the support and
a patch for the dt-bindings.
