Hi All,

This patch series introduces the Andes PMU extension, which serves the
same purpose as Sscofpmf and Smcntrpmf. Its non-standard local interrupt
is assigned to bit 18 in the custom S-mode local interrupt enable and
pending registers (slie/slip), while the interrupt cause is (256 + 18).

The series can be found on Andes Technology GitHub:
- https://github.com/andestech/linux/commits/andes-pmu-support-v9

The PMU device tree node used on AX45MP:
