[PATCH 0/2] cpufreq: CPPC: Avoid cur frequency modification on governor start

[Prashant Malani <pmalani@google.com>]

This is a short series that handles an issue where, on CPPC-based systems,
the cpu frequency was getting unintentionally set to the wrong value on
governor start ( and overriding the existing policy frequency) because of
unreliable AMU/CPPC counters.

This adds a governor flag that avoids the check against the CPPC AMU-based
frequency when the governor starts. It then modifies the CPPC CPU freq
driver to opt in to using this flag.

Prashant Malani (2):
  cpufreq: Add driver flag to avoid initial frequency verification
  cpufreq: CPPC: Don't verify cur frequency on governor start
