Merge tag 'devfreq-next-for-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for 5.11 from Chanwoo Choi:

1. Update devfreq core

- Add new devfreq_frequency tracepoint to show the frequency change
information.

- Add governor feature flag. The devfreq governor is able to set the
specific flag in order to support a non-common feature. For
example, if the governor supports the 'immutable' feature, don't
allow user space to change the governor via sysfs.

- Add governor sysfs attribute flag for each sysfs file. Prior to that
the devfreq subsystem allowed all of the sysfs files to be accessed
regardless of the governor type. But some sysfs fils are not
supported by specific devfreq governors. In order to only allow the
sysfs files supported by the governor to be accessed, clarify the
access permissions of sysfs attributes according to the governor.
When adding the devfreq governor, specify the available attribute
information by using DEVFREQ_GOV_ATTR_* symbols. The user can read
or write the sysfs attributes in accordance to the specified
access permissions.

- Clean-up the code to reduce duplication for the devfreq tracepoint
and to remove redundant governor_name field from struct devfreq.

2. Update exynos-bus.c devfreq driver

- Add interconnect API support to the Samsung Exynos Bus Frequency
driver, exynos-bus.c. Complementing the devfreq driver with
interconnect functionality allows to ensure that the QoS
requirements regarding devices accessing the system memory (e.g.
video processing devices) will be met and allows to avoid issues
like DMA underrun.

3. Update tegra devfreq driver

- Add interconnect support and OPP interface to tegra30-devfreq.c.
Also, it is to guarantee the QoS requirement of some devices like
the display controller.

- Move tegra20-devfreq.c from drivers/devfreq/ into drivers/memory/tegra/
in order to use the more proper monitoring feature such as EMC_STAT
which is located in drivers/memory/tegra/.

- Separate the configuration information for different SoCs in
tegra30-devfrqe.c. The tegra30-devfreq.c had been supporting both
tegra30-actmon and tegra124-actmon devices. In order to use the
more correct configuration data, separate them.

- Use dev_err_probe() to handle the deferred probe error in
tegra30-devfreq.c.

4. Pull the request of 'Tegra SoC and clock controller changes for
v5.11' sent by Krzysztof Kozlowski <krzk@kernel.org> in order to

PM / devfreq: Add governor feature flag

The devfreq governor is able to have the specific flag as follows
in order to implement the specific feature. For example, devfreq allows
user to change the governors on runtime via sysfs interface.
But, if devfreq device uses 'passive' governor, don't allow user to change
the governor. For this case, define the DEVFREQ_GOV_FLAG_IMMUTABLE
and set it to flag of passive governor.

[Definition for governor flag]
- DEVFREQ_GOV_FLAG_IMMUTABLE
: If immutable flag is set, governor is never changeable to other governors.
- DEVFREQ_GOV_FLAG_IRQ_DRIVEN
: Devfreq core won't schedule polling work for this governor if value is set.

[Table of governor flag for devfreq governors]

Merge tag 'pm-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These include a rework of the main suspend-to-idle code flow (related
to the handling of spurious wakeups), a switch over of several users
of cpufreq notifiers to QoS-based limits, a new devfreq driver for
Tegra20, a new cpuidle driver and governor for virtualized guests, an
extension of the wakeup sources framework to expose wakeup sources as
device objects in sysfs, and more.

Specifics:

- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).

- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).

- Expose system suspend statistics in sysfs (Kalesh Singh).

- Introduce a new haltpoll cpuidle driver and a new matching governor
for virtualized guests wanting to do guest-side polling in the idle
loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).

- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).

- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel
Lezcano).

- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).

- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).

- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).

- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).

- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).

- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).

- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).

- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).

- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).

- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).

- Improve devfreq documentation and governor code, fix spelling typos
in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
MyungJoo Ham, Gaël PORTAY).

- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).

- Update the OPP framework to support multiple opp-suspend properties
(Anson Huang).

- Fix assorted issues and make assorted minor improvements in the OPP
code (Niklas Cassel, Viresh Kumar, Yue Hu).

- Clean up the generic power domains (genpd) framework (Ulf Hansson).

- Clean up assorted pieces of power management code and documentation
(Akinobu Mita, Amit Kucheria, Chuhong Yuan).

- Update the pm-graph tool to version 5.5 including multiple fixes
and improvements (Todd Brandt).

- Update the cpupower utility (Benjamin Weis, Geert Uytterhoeven,
Sébastien Szymanski)"
