Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.9-rc1

with top-most commit 866b554c2d3e067751cc2cbad9ed281db2d47143

 Merge tag 'opp-updates-6.9' of
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm into pm

on top of commit f0a0fc10abb062d122db5ac4ed42f6d1ca342649

 cpufreq: intel_pstate: fix pstate limits enforcement for adjust_perf call =
back

to receive power management updates for 6.9-rc1.

From the functional perspective, the most significant change here is the
addition of support for Energy Models that can be updated dynamically
at run time.  There is also the addition of LZ4 compression support for
hibernation, the new preferred core support in amd-pstate, new platforms
support in the Intel RAPL driver, new model-specific EPP handling in
intel_pstate and more.

Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system suspend
statistics code undergoes a significant rework and there is a usual
bunch of fixes and code cleanups all over.

Specifics:

 - Allow the Energy Model to be updated dynamically (Lukasz Luba).

 - Add support for LZ4 compression algorithm to the hibernation image
   creation and loading code (Nikhil V).

 - Fix and clean up system suspend statistics collection (Rafael
   Wysocki).

 - Simplify device suspend and resume handling in the power management
   core code (Rafael Wysocki).

 - Fix PCI hibernation support description (Yiwei Lin).

 - Make hibernation take set_memory_ro() return values into account as
   appropriate (Christophe Leroy).

 - Set mem_sleep_current during kernel command line setup to avoid an
   ordering issue with handling it (Maulik Shah).

 - Fix wake IRQs handling when pm_runtime_force_suspend() is used as a
   driver's system suspend callback (Qingliang Li).

 - Simplify pm_runtime_get_if_active() usage and add a replacement for
   pm_runtime_put_autosuspend() (Sakari Ailus).

 - Add a tracepoint for runtime_status changes tracking (Vilas Bhat).

 - Fix section title markdown in the runtime PM documentation (Yiwei
   Lin).

 - Enable preferred core support in the amd-pstate cpufreq driver (Meng
   Li).

 - Fix min_perf assignment in amd_pstate_adjust_perf() and make the
   min/max limit perf values in amd-pstate always stay within the
   (highest perf, lowest perf) range (Tor Vic, Meng Li).

 - Allow intel_pstate to assign model-specific values to strings used in
   the EPP sysfs interface and make it do so on Meteor Lake (Srinivas
   Pandruvada).

 - Drop long-unused cpudata::prev_cummulative_iowait from the
   intel_pstate cpufreq driver (Jiri Slaby).

 - Prevent scaling_cur_freq from exceeding scaling_max_freq when the
   latter is an inefficient frequency (Shivnandan Kumar).

 - Change default transition delay in cpufreq to 2ms (Qais Yousef).

 - Remove references to 10ms minimum sampling rate from comments in the
   cpufreq code (Pierre Gondois).

 - Honour transition_latency over transition_delay_us in cpufreq (Qais
   Yousef).

 - Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar).

 - General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
   N=C3=ADcolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
   Belova).

 - Update cpufreq-dt-platdev to block/approve devices (Richard Acayan).

 - Make the SCMI cpufreq driver get a transition delay value from
   firmware (Pierre Gondois).

 - Prevent the haltpoll cpuidle governor from shrinking guest
   poll_limit_ns below grow_start (Parshuram Sangle).

 - Avoid potential overflow in integer multiplication when computing
   cpuidle state parameters (C Cheng).

 - Adjust MWAIT hint target C-state computation in the ACPI cpuidle
   driver and in intel_idle to return a correct value for C0 (He
   Rongguang).

 - Address multiple issues in the TPMI RAPL driver and add support for
   new platforms (Lunar Lake-M, Arrow Lake) to Intel RAPL (Zhang Rui).

 - Fix freq_qos_add_request() return value check in dtpm_cpu (Daniel
   Lezcano).

 - Fix kernel-doc for dtpm_create_hierarchy() (Yang Li).

 - Fix file leak in get_pkg_num() in x86_energy_perf_policy (Samasth
   Norway Ananda).

 - Fix cpupower-frequency-info.1 man page typo (Jan Kratochvil).

 - Fix a couple of warnings in the OPP core code related to W=3D1
   builds (Viresh Kumar).

 - Move dev_pm_opp_{init|free}_cpufreq_table() to pm_opp.h (Viresh
   Kumar).

 - Extend dev_pm_opp_data with turbo support (Sibi Sankar).

 - dt-bindings: drop maxItems from inner items (David Heidelberg).

Thanks!
