Merge branch 'pm-cpufreq'

Merge cpufreq updates for 6.7-rc1:

 - Add support for several Qualcomm SoC versions and other similar
   changes (Christian Marangi, Dmitry Baryshkov, Luca Weiss, Neil
   Armstrong, Richard Acayan, Robert Marko, Rohit Agarwal, Stephan
   Gerhold and Varadarajan Narayanan).

 - Clean up the tegra cpufreq driver (Sumit Gupta).

 - Use of_property_read_reg() to parse "reg" in pmac32 driver (Rob
   Herring).

 - Add support for TI's am62p5 Soc (Bryan Brattlof).

 - Make ARM_BRCMSTB_AVS_CPUFREQ depends on !ARM_SCMI_CPUFREQ (Florian
   Fainelli).

 - Update Kconfig to mention i.MX7 as well (Alexander Stein).

 - Revise global turbo disable check in intel_pstate (Srinivas
   Pandruvada).

 - Carry out initialization of sg_cpu in the schedutil cpufreq governor
   in one loop (Liao Chang).

 - Simplify the condition for storing 'down_threshold' in the
   conservative cpufreq governor (Liao Chang).

 - Use fine-grained mutex in the userspace cpufreq governor (Liao
   Chang).

 - Move is_managed indicator in the userspace cpufreq governor into a
   per-policy structure (Liao Chang).

 - Rebuild sched-domains when removing cpufreq driver (Pierre Gondois).

 - Fix buffer overflow detection in trans_stats() (Christian Marangi).
