- Add new power capping facility called DTPM (Dynamic Thermal Power
Management), based on the existing power capping framework, to
allow aggregate power constraints to be applied to sets of devices
in a distributed manner, along with a CPU backend driver based on
the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King).
- Add AlderLake Mobile support to the Intel RAPL power capping
driver and make it use the topology interface when laying out the
system topology (Zhang Rui, Yunfeng Ye).
- Drop the cpufreq tango driver belonging to a platform that is not
supported any more (Arnd Bergmann).
- Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq
driver flags (Viresh Kumar).
- Update cpufreq drivers:
* Fix max CPU frequency discovery in the intel_pstate driver and
make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
Christian).
* Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe
JAILLET).
* Make the tegra20 driver use the resource-managed API (Dmitry
Osipenko).
* Enable boost support in the qcom-hw driver (Shawn Guo).
- Update the operating performance points (OPP) framework:
* Clean up the OPP core (Dmitry Osipenko, Viresh Kumar).
* Extend the OPP API by adding new helpers to it (Dmitry Osipenko,
Viresh Kumar).
* Allow required OPPs to be used for devfreq devices and update
the devfreq governor code accordingly (Saravana Kannan).
* Prepare the framework for introducing new dev_pm_opp_set_opp()
helper (Viresh Kumar).
* Drop dev_pm_opp_set_bw() and update related drivers (Viresh
Kumar).
* Allow lazy linking of required-OPPs (Viresh Kumar).
- Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
Pierre Kuo).
- Update the generic power domains (genpd) framework:
* Use device's next wakeup to determine domain idle state (Lina
Iyer).
* Improve initialization and debug (Dmitry Osipenko).
* Simplify computations (Abaci Team).
- Make janitorial changes in the core code handling system sleep
and PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,
Zqiang).
- Update the MAINTAINERS entry for the exynos cpuidle driver and
drop DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom
Rix).
- Extend the PM clock layer to cover clocks that must sleep (Nicolas
Pitre).
- Update the cpupower utility:
* Update cpupower command, add support for AMD family 0x19 and clean
up the code to remove many of the family checks to make future
family updates easier (Nathan Fontenot, Robert Richter).
* Add Makefile dependencies for install targets to allow building
cpupower in parallel rather than serially (Ivan Babrou).
- Make janitorial changes in power management Kconfig (Lukasz Luba).

Pull power management updates from Rafael Wysocki:
"These add a new power capping facility allowing aggregate power
constraints to be applied to sets of devices in a distributed manner,

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
