Subject: [PATCH v6 0/3] RISC-V: Create unique identification for SoC PMU
Date:   Mon, 15 Aug 2022 16:22:37 +0300

This series aims to provide matching vendor SoC with corresponded JSON bindings.

The ID string is proposed to be in form of MVENDORID-MARCHID-MIMPID, for example
for Sifive Unmatched the corresponding string will be:

0x489-0x8000000000000007-0x[[:xdigit:]]+,v1,sifive/u74,core

Where MIMPID can vary as all impl supported the same number of events, this might not
be true for all future SoC however.

Also added SBI firmware events pretty names, as any firmware that supports SBI PMU
should also support firmare events [1].

Series depends on patch by Anup Patel, exposing mvendor, marchid and mimpid
to "/proc/cpuinfo" [2].

Tested with the following OpenSBI device tree bindings:

```

        compatible = "riscv,pmu";
