Merge tag 'pm-5.3-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These modify the Intel RAPL driver to allow it to use an MMIO
  interface to the hardware, make the int340X thermal driver provide
  such an interface for it, add Intel Ice Lake CPU IDs to the RAPL
  driver (these changes depend on the previously merged x86 arch
  changes), update cpufreq to use the PM QoS framework for managing the
  min and max frequency limits, and add update the imx-cpufreq-dt
  cpufreq driver to support i.MX8MN.

  Specifics:

   - Add MMIO interface support to the Intel RAPL power capping driver
     and update the int340X thermal driver to provide a RAPL MMIO
     interface (Zhang Rui, Stephen Rothwell).

   - Add Intel Ice Lake CPU IDs to the RAPL driver (Zhang Rui, Rajneesh
     Bhardwaj).

   - Make cpufreq use the PM QoS framework (instead of notifiers) for
     managing the min and max frequency constraints (Viresh Kumar).

   - Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
     Huang)"
