Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.

As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.

Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

Specifics:

- Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef)

- Add support for Granite Rapids and Sierra Forest in OOB mode to the
intel_pstate cpufreq driver (Srinivas Pandruvada)

- Add basic support for CPU capacity scaling on x86 and make the
intel_pstate driver set asymmetric CPU capacity on hybrid systems
without SMT (Rafael Wysocki)

- Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq
driver (Jeff Johnson)

- Several OF related cleanups in cpufreq drivers (Rob Herring)

- Enable COMPILE_TEST for ARM drivers (Rob Herrring)

- Introduce quirks for syscon failures and use socinfo to get
revision for TI cpufreq driver (Dhruva Gole, Nishanth Menon)

- Minor cleanups in amd-pstate driver (Anastasia Belova, Dhananjay
Ugwekar)

- Minor cleanups for loongson, cpufreq-dt and powernv cpufreq drivers
(Danila Tikhonov, Huacai Chen, and Liu Jing)

- Make amd-pstate validate return of any attempt to update EPP
limits, which fixes the masking hardware problems (Mario
Limonciello)

- Move the calculation of the AMD boost numerator outside of
amd-pstate, correcting acpi-cpufreq on systems with preferred cores
(Mario Limonciello)

- Harden preferred core detection in amd-pstate to avoid potential
false positives (Mario Limonciello)

- Add extra unit test coverage for mode state machine (Mario
Limonciello)

- Fix an "Uninitialized variables" issue in amd-pstste (Qianqiang
Liu)

- Add Granite Rapids Xeon support to intel_idle (Artem Bityutskiy)

- Disable promotion to C1E on Jasper Lake and Elkhart Lake in
intel_idle (Kai-Heng Feng)

- Use scoped device node handling to fix missing of_node_put() and
simplify walking OF children in the riscv-sbi cpuidle driver
(Krzysztof Kozlowski)

- Remove dead code from cpuidle_enter_state() (Dhruva Gole)

- Change an error pointer to NULL to fix error handling in the
intel_rapl power capping driver (Dan Carpenter)

- Fix off by one in get_rpi() in the intel_rapl power capping driver
(Dan Carpenter)

- Add support for ArrowLake-U to the intel_rapl power capping driver
(Sumeet Pawnikar)

- Fix the energy-pkg event for AMD CPUs in the intel_rapl power
capping driver (Dhananjay Ugwekar)

- Add support for AMD family 1Ah processors to the intel_rapl power
capping driver (Dhananjay Ugwekar)

- Remove unused stub for saveable_highmem_page() and remove
deprecated macros from power management documentation (Andy
Shevchenko)

- Use ysfs_emit() and sysfs_emit_at() in "show" functions in the PM
sysfs interface (Xueqin Luo)

- Update the maintainers information for the
operating-points-v2-ti-cpu DT binding (Dhruva Gole)

- Drop unnecessary of_match_ptr() from ti-opp-supply (Rob Herring)

- Add missing MODULE_DESCRIPTION() macros to devfreq governors (Jeff
Johnson)

- Use devm_clk_get_enabled() in the exynos-bus devfreq driver (Anand
Moon)

- Use of_property_present() instead of of_get_property() in the
imx-bus devfreq driver (Rob Herring)

- Update directory handling and installation process in the pm-graph
Makefile and add .gitignore to ignore sleepgraph.py artifacts to
pm-graph (Amit Vadhavana, Yo-Jung Lin)

- Make cpupower display residency value in idle-info (Aboorva
Devarajan)

- Add missing powercap_set_enabled() stub function to cpupower (John
B. Wyatt IV)

- Add SWIG support to cpupower (John B. Wyatt IV)"

Merge tag 'linux-cpupower-6.12-rc1-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shuah/linux

Merge the second round of cpupower utility updates for 6.12-rc1 from
Shuah Khan:

"This cpupower second update for Linux 6.12-rc1 consists of a fix
and a new feature.

-- adds missing powercap_set_enabled() stub function
-- adds SWIG bindings files for libcpupower

SWIG is a tool packaged in Fedora and other distros that can generate
bindings from C and C++ code for several languages including Python,
Perl, and Go.

These bindings allows users to easily write scripts that use and extend
libcpupower's functionality. Currently, only Python is provided in the
makefile, but additional languages may be added if there is demand.

Note that while SWIG itself is GPL v3+ licensed; the resulting output,
the bindings code, is permissively licensed + the license of the .o
files. Please see the following for more details.
