[PATCH v2 0/3] cppc_cpufreq: Rework ->get() error handling when cores are idle

[Jie Zhan <zhanjie9@xxxxxxxxxxxxx>]

CPPC feedback counters can be unchanged or 0 when cores are idle, e.g.
clock-gated or power-gated.  In such case, get the latest desired perf for
calculating frequency.  Also, the HiSilicon CPPC workaround is now handled
by the common code and can be removed.

Jie Zhan (3):
  cppc_cpufreq: Return desired perf in ->get() if feedback counters are
    0
  cppc_cpufreq: Return latest desired perf if feedback counters don't
    change
  cppc_cpufreq: Remove HiSilicon CPPC workaround
