Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.
Specifics:
- Make the Energy Model cover non-CPU devices (Lukasz Luba).
- Add Ice Lake server idle states table to the intel_idle driver and
eliminate a redundant static variable from it (Chen Yu, Rafael
Wysocki).
- Eliminate all W=1 build warnings from cpufreq (Lee Jones).
- Add support for Sapphire Rapids and for Power Limit 4 to the Intel
RAPL power capping driver (Sumeet Pawnikar, Zhang Rui).
- Fix function name in kerneldoc comments in the idle_inject power
capping driver (Yangtao Li).
- Fix locking issues with cpufreq governors and drop a redundant
"weak" function definition from cpufreq (Viresh Kumar).
- Rearrange cpufreq to register non-modular governors at the
core_initcall level and allow the default cpufreq governor to be
specified in the kernel command line (Quentin Perret).
- Extend, fix and clean up the intel_pstate driver (Srinivas
Pandruvada, Rafael Wysocki):
* Add a new sysfs attribute for disabling/enabling CPU
energy-efficiency optimizations in the processor.
* Make the driver avoid enabling HWP if EPP is not supported.
* Allow the driver to handle numeric EPP values in the sysfs
interface and fix the setting of EPP via sysfs in the active
mode.
* Eliminate a static checker warning and clean up a kerneldoc
comment.
- Clean up some variable declarations in the powernv cpufreq driver
(Wei Yongjun).
- Fix up the ->enter_s2idle callback definition to cover the case
when it points to the same function as ->idle correctly (Neal Liu).
- Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).
- Make the PM core emit "changed" uevent when adding/removing the
"wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).
- Add a helper macro for declaring PM callbacks and use it in the MMC
jz4740 driver (Paul Cercueil).
- Fix white space in some places in the hibernate code and make the
system-wide PM code use "const char *" where appropriate (Xiang
Chen, Alexey Dobriyan).
- Add one more "unsafe" helper macro to the freezer to cover the NFS
use case (He Zhe).
- Change the language in the generic PM domains framework to use
parent/child terminology and clean up a typo and some comment
fromatting in that code (Kees Cook, Geert Uytterhoeven).
- Update the operating performance points OPP framework (Lukasz Luba,
Andrew-sh.Cheng, Valdis Kletnieks):
* Refactor dev_pm_opp_of_register_em() and update related drivers.
* Add a missing function export.
* Allow disabled OPPs in dev_pm_opp_get_freq().
- Update devfreq core and drivers (Chanwoo Choi, Lukasz Luba, Enric
Balletbo i Serra, Dmitry Osipenko, Kieran Bingham, Marc Zyngier):
* Add support for delayed timers to the devfreq core and make the
Samsung exynos5422-dmc driver use it.
* Unify sysfs interface to use "df-" as a prefix in instance
names consistently.
* Fix devfreq_summary debugfs node indentation.
* Add the rockchip,pmu phandle to the rk3399_dmc driver DT
bindings.
* List Dmitry Osipenko as the Tegra devfreq driver maintainer.
* Fix typos in the core devfreq code.
- Update the pm-graph utility to version 5.7 including a number of
fixes related to suspend-to-idle (Todd Brandt).
- Fix coccicheck errors and warnings in the cpupower utility (Shuah
Khan).
- Replace HTTP links with HTTPs ones in multiple places (Alexander A.
Klimov)"

Pull spi updates from Mark Brown:
"A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity.
This includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the
memory subsystem doesn't seem to have a fixed maintainer at the minute
and this seemed like the most sensible way to get that hardware
supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm
GENI, sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and

The driver can operate in two modes relaying on devfreq monitoring
mechanism which periodically checks the device status or it can use
interrupts when they are provided by loaded Device Tree. The newly
introduced module parameter can be used to choose between devfreq
monitoring and internal interrupts without modifying the Device Tree.
It also sets devfreq monitoring as default when the parameter is not set
(also the case for default when the driver is not built as a module).

The driver only uses the registers up to offset 0x54. Since the EFUSE
registers are in the middle of the NEMC registers, we only request
the registers we will use for now - that way the EFUSE driver can

Memory controller drivers for v5.9
The drivers/memory directory with memory controller drivers, over the
last days grew in numbers but lacked any coordinated care. The generic
part (device tree helpers) were pulled in through various trees,
depending on driver needs.
The patchset is a first try to improve code quality of memory controller
drivers. Mostly these are non-intrusive fixes for GCC, checkpatch or
sparse warnings. This also fixes missing SPDX tags or improves generic
code quality (whitespace, const correctness).
Last commit appoints also Krzysztof Kozlowski as a maintainer.

following write in exynos5_switch_timing_regs(). Pass reading error

Commit a127e690b051 ("memory: tegra: Add support for the Tegra194 memory

CONFIG_ARCH_TEGRA186_SOC and CONFIG_ARCH_TEGRA194_SOC to the Tegra EMC
driver. These KCONFIG variables do not exist and prevent the EMC driver
from being probed on Tegra186 and Tegra194. These KCONFIG variable
names are simply missing one underscore and so fix this by adding the
necessary underscore to the variable names.

The memory clock-rate change could be running on a non-boot CPU, while the
boot CPU handles the EMC interrupt. This introduces an unnecessary latency
since boot CPU should handle the interrupt and then notify the sibling CPU
about clock-rate change completion. In some rare cases boot CPU could be
in uninterruptible state for a significant time (like in a case of KASAN +
NFS root), it could get to the point that completion timeouts before boot
CPU gets a chance to handle interrupt. The solution is to get rid of the
completion and replace it with interrupt-status polling.
