Pull devfreq changes for 5.19-rc1 from Chanwoo Choi:

"1. Update devfreq core

 - Add cpu based scaling support to passive governor. Some device like
   cache might require the dynamic frequency scaling. But, it has very
   tightly to cpu frequency. So that use passive governor to scale
   the frequency according to current cpu frequency.

  To decide the frequency of the device, the governor does one of the following:
  : Derives the optimal devfreq device opp from required-opps property of
    the parent cpu opp_table.

  : Scales the device frequency in proportion to the CPU frequency. So, if
    the CPUs are running at their max frequency, the device runs at its
    max frequency. If the CPUs are running at their min frequency, the
    device runs at its min frequency. It is interpolated for frequencies
    in between.

 2. Update devfreq drivers

  - Update rk3399_dmc.c as following:

   : Convert dt-binding document to YAML and deprecate unused properties.

   : Use Hz units for the device-tree properties of rk3399_dmc.

   : rk3399_dmc is able to set the idle time before changing the dmc clock.
     Specify idle time parameters by using nano-second unit on dt bidning.

   : Add new disable-freq properties to optimize the power-saving feature
     of rk3399_dmc.

   : Disable devfreq-event device on remove() to fix unbalanced
     enable-disable count.

   : Use devm_pm_opp_of_add_table()

   : Block PMU (Power-Management Unit) transitions when scaling frequency
     by ARM Trust Firmware in order to fix the conflict between PMU and DMC
     (Dynamic Memory Controller)."
