Merge branch 'pm-cpufreq'

Merge cpufreq changes for 6.11-rc1:

 - Add Loongson-3 CPUFreq driver support (Huacai Chen).

 - Add support for the Arrow Lake and Lunar Lake platforms and
   the out-of-band (OOB) mode on Emerald Rapids to the intel_pstate
   cpufreq driver, make it support the highest performance change
   interrupt and clean it up (Srinivas Pandruvada).

 - Switch cpufreq to new Intel CPU model defines (Tony Luck).

 - Simplify the cpufreq driver interface by switching the .exit() driver
   callback to the void return data type (Lizhe, Viresh Kumar).

 - Make cpufreq_boost_enabled() return bool (Dhruva Gole).

 - Add fast CPPC support to the amd-pstate cpufreq driver, address
   multiple assorted issues in it and clean it up (Perry Yuan, Mario
   Limonciello, Dhananjay Ugwekar, Meng Li, Xiaojian Du).

 - Add Allwinner H700 speed bin to the sun50i cpufreq driver (Ryan
   Walklin).

 - Fix memory leaks and of_node_put() usage in the sun50i and qcom-nvmem
   cpufreq drivers (Javier Carrasco).

 - Clean up the sti and dt-platdev cpufreq drivers (Jeff Johnson,
   Raphael Gallais-Pou).

 - Fix deferred probe handling in the TI cpufreq driver and wrong return
   values of ti_opp_supply_probe(), and add OPP tables for the AM62Ax and
   AM62Px SoCs to it (Bryan Brattlof, Primoz Fiser).

 - Avoid overflow of target_freq in .fast_switch() in the SCMI cpufreq
   driver (Jagadeesh Kona).

 - Use dev_err_probe() in every error path in probe in the Mediatek
   cpufreq driver (Nícolas Prado).

 - Fix kernel-doc param for longhaul_setstate in the longhaul cpufreq
   driver (Yang Li).

 - Fix system resume handling in the CPPC cpufreq driver (Riwen Lu).

+``boost``
+The `boost` sysfs attribute provides control over the CPU core
+performance boost, allowing users to manage the maximum frequency limitation
+of the CPU. This attribute can be used to enable or disable the boost feature
+on individual CPUs.
+
+When the boost feature is enabled, the CPU can dynamically increase its frequency
+beyond the base frequency, providing enhanced performance for demanding workloads.
+On the other hand, disabling the boost feature restricts the CPU to operate at the
+base frequency, which may be desirable in certain scenarios to prioritize power
+efficiency or manage temperature.
+
+To manipulate the `boost` attribute, users can write a value of `0` to disable the
+boost or `1` to enable it, for the respective CPU using the sysfs path
+`/sys/devices/system/cpu/cpuX/cpufreq/boost`, where `X` represents the CPU number.

 Other performance and frequency values can be read back from
 ``/sys/devices/system/cpu/cpuX/acpi_cppc/``, see :ref:`cppc_sysfs`.
