      Abhilash Jindal authored
      Wall time obtained from do_gettimeofday is susceptible to sudden jumps due to
      user setting the time or due to NTP.
      
      Monotonic time is constantly increasing time better suited for comparing two
      timestamps.

      Its all about caching min/max freq requested by userspace, and
      the name 'cpufreq_real_policy' doesn't fit that well. Rename it to
      cpufreq_user_policy.

      cpufreq: update user_policy.* on success · 14ca0bdf
      Viresh Kumar authored
      'user_policy' caches properties of a policy that are set by userspace.
      And these must be updated only if cpufreq core was successful in
      updating them based on request from user space.
      
      In store_scaling_governor(), we are updating user_policy.policy and
      user_policy.governor even if cpufreq_set_policy() failed. That's
      incorrect.
      
      Fix this by updating user_policy.* only if we were successful in
      updating the properties.

      cpufreq: use memcpy() to copy policy · 8fa5b631
      Viresh Kumar authored
      cpufreq_get_policy() is useful if the pointer to policy isn't available
      in advance. But if it is available, then there is no need to call
      cpufreq_get_policy(). Directly use memcpy() to copy the policy.

      cpufreq: remove redundant CPUFREQ_INCOMPATIBLE notifier event · 6bfb7c74
      Viresh Kumar authored
      What's being done from CPUFREQ_INCOMPATIBLE, can also be done with
      CPUFREQ_ADJUST. There is nothing special with CPUFREQ_INCOMPATIBLE
      notifier.
      
      Kill CPUFREQ_INCOMPATIBLE and fix its usage sites.
      
      This also updates the numbering of notifier events to remove holes.

      cpufreq: mediatek: Add MT8173 cpufreq driver · 1453863f
      Pi-Cheng Chen authored
      Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and
      2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage
      inputs, Vproc and Vsram are supplied by two regulators. For the big
      cluster, two regulators come from different PMICs. In this case, when
      scaling voltage inputs of the cluster, the voltages of two regulator
      inputs need to be controlled by software explicitly under the SoC
      specific limitation:
      
      	100mV < Vsram - Vproc < 200mV
      
      which is called 'voltage tracking' mechanism. And when scaling the
      frequency of cluster clock input, the input MUX need to be parented to
      another "intermediate" stable PLL first and reparented to the original
      PLL once the original PLL is stable at the target frequency. This patch
      implements those mechanisms to enable CPU DVFS support for Mediatek
      MT8173 SoC.
