Subject: [PATCH V2 0/4] Add tracer tool for AMD P-State driver

Hello,

intel_pstate_tracer is a useful tool to analyze the performance of
intel_pstate driver. We upstream out AMD P-state driver into Linux
kernel recently and like to use similar tool to tune the performance
of the driver.

I modified intel_pstate_tracer.py then it could import as a module to
analyze AMD P-State trace event. Other trace event also can benifit from
this change once they need this tool.

intel_pstate_tracer could be used as the same way as before and the
original functionality isn't broken.

Changes from V1->V2
-Add tracer documentation in amd-pstate RST
-fix typo in amd_pstate_trace.py
-add "Co-developed-by" in patch 1/4

Thanks,
Joe
