cpuidle: use default_groups in kobj_type
There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the cpuidle sysfs code to use default_groups field which
has been the preferred way since

cpuidle: Fix cpuidle_remove_state_sysfs() kerneldoc comment
Fix function name in sysfs.c kernel-doc comment to remove a warning found by running scripts/kernel-doc, which is caused by using 'make W=1'. drivers/cpuidle/sysfs.c:512: warning: expecting prototype for cpuidle_remove_driver_sysfs().

ARM: SoC drivers for 5.16
These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

Qualcomm driver updates for v5.16
This drops the use of power-domains for exposing the load_state from the QMP driver to clients, to avoid issues related to system suspend. SMP2P becomes wakeup capable, to allow dying remoteprocs to wake up Linux from suspend to perform recovery. It adds RPM power-domain support for SM6350 and MSM8953 and base RPM support for MSM8953 and QCM2290. It adds support for MSM8996, SDM630 and SDM660 in the SPM driver, which will enable the introduction of proper voltage scaling of the CPU subsystem. Support for releasing secondary CPUs on MSM8226 is introduced. The Asynchronous Packet Router (APR) driver is extended to support the new Generic Packet Router (GPR) variant, which is used to communicate with the firmware in the new AudioReach audio driver. Lastly it transitions a number of drivers to safer string functions, as well as switching things to use devm_platform_ioremap_resource(). -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmFlxugbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F3A0P/ixLiu0XktPOyFZ+3Ag/ 5KKan6wlH8JO0AfxbOolk0MkC1/8uk1V+Kuw4b/22jTO4w/9Illi9jSmV0wR3IBh 26sWpyxNK7N+7uAnBDqlZekQYTg5xKqJGn69kxe0oIm8yAogGkxZnlIWt7JGtWS0 NcyLLe9gS/B/q6ppTkxlYhSMB3Qp6bU/lRjBWTcHlxaNxGyNbGw4zp5ncze8ui9R s0JdFhJ/T1ptuWuIhrEWXEVapQtf0pgPvYSWxRYoBRU4N1F4HcRcLVpUU6eSvFEg BKxN11dCW4o0njLBpdPtg3u7AL31A95OPFiVwpWEb6Wov1DAdQYfYSoc7r2uqKvL QgvE/Fq1uPNPsFH2AgJjmku7nb2S0UP2msIhsZjugwxCQXtHgv2uPdYSN/MOudEZ MdjbbAHKW9+TR4gTVzA7b7OVzB73+tjHo/4hUjy8J5RlRKujbzHHXLRjvpNAILqn y457eUFqYxR1C3CKy2GrgR/PvNcBdDVq0ikuv4elYZEIaPL/Wxg6V7RJSHzgAgU/ 7XArrGvCXdLXy/e07KJ4Su74OBOsXnqLLr+Xsw5+h42XCnDfmI3caQlQjTXxJxN4 EifHOoPCa8JNtXzWKSBSO7Pb5teSYh5XlAQs8nGVbrKMhly/MDLeNzSL+uu8DGNw B9Cf/mM9bhs3Q69Z37WgOdK0 =FE4j -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmFnQuMACgkQmmx57+YA GNk90g/9F5Sh8wfMQ3WYZMu10L431dXYKkafccK8SFgNhTxTuJ7xPbJzXxFQW6Qp Ky0DAKcJB/tW/jCMh7L/d7pET4tedRncZd6Pk8kkn8uRC9qiTEFyPKP+4trADnhw Q/gf8xbEJz13aDzFbfW2Ko9Rx0HJQ/BSWVzZ5fpkUmoSSBnxm+rq9T3e10BNX1QT /Bg1M77zyYWtlPKexjxBEz7EZuQIEmN9gkCCriYTMw34hfVYszsNkIZnIGfe/wAa F6iSjIwVqf4DbM6QzabNoCUzZf50Ij4Vdlhvk5FUt3quPIvcULzIxQxI3o/J5sJ2 2mowPuiVjmqx4R8XFILod0+KU4NNUGcb2YFLZg+XjbopArfLZaa2OV40m2QDY/Ay /BHXBtxLDDcDqwOX6Y7NEfbNFUqLlFv00vuZEJ9KT/19ZfJgCw4qoxw44aldjQEo 3pvEACOHLKoI+FOeb6LHL0erfc1jz/qul37oWI361rDIfWsWsZtbyc+gItMDLGYa C1qUHoP5vMmse0tILT6AJNR23aGJFapKkzTNWB6j5Pi/0sdv3zGbhxubf+TxMRtx 5BhEP2N5pHdKVopxVSG2JVOtT12jE68tV0E00erEoPIG35C+DyADn5i9lg4g20Ix MwxwtgAC0cws8tpwsDvFOCj8SPn9HDtEGMJMejo5xuEIxqjAb2E= =LLU7 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.16 This drops the use of power-domains for exposing the load_state from the QMP driver to clients, to avoid issues related to system suspend.

mfd/cpuidle: ux500: Rename driver symbol
The PRCMU driver defines this as a DT node but there are no bindings for it and it needs no data from the device tree. Just spawn the device directly in the same way as the watchdog. Name it "db8500-cpuidle" since there are no ambitions to support any more SoCs than this one. This rids this annoying boot message: [ 0.032610] cpuidle-dbx500: Failed to locate of_node [id: 0] However I think the device still spawns and work just fine, despite not finding a device tree node.

cpuidle: pseries: Mark pseries_idle_proble() as __init
After commit 7cbd631d4dec ("cpuidle: pseries: Fixup CEDE0 latency only
for POWER10 onwards"), pseries_idle_probe() is no longer inlined when
compiling with clang, which causes a modpost warning:
WARNING: modpost: vmlinux.o(.text+0xc86a54): Section mismatch in
reference from the function pseries_idle_probe() to the function
.init.text:fixup_cede0_latency()
The function pseries_idle_probe() references
the function __init fixup_cede0_latency().
This is often because pseries_idle_probe lacks a __init
annotation or the annotation of fixup_cede0_latency is wrong.
pseries_idle_probe() is a non-init function, which calls
fixup_cede0_latency(), which is an init function, explaining the
mismatch. pseries_idle_probe() is only called from
pseries_processor_idle_init(), which is an init function, so mark
pseries_idle_probe() as __init so there is no more warning.

cpuidle: teo: Fix alternative idle state lookup
There are three mistakes in the loop in teo_select() that is looking
for an alternative candidate idle state. First, it should walk all
of the idle states shallower than the current candidate one,
including all of the disabled ones, but it terminates after the first
enabled idle state. Second, it should not terminate its last step
if idle state 0 is disabled (which is related to the first issue).
Finally, it may return the current alternative candidate idle state
prematurely if the time span criterion is not met by the idle state
under consideration at the moment.
To address the issues mentioned above, make the loop in question walk
all of the idle states shallower than the current candidate idle state
all the way down to idle state 0 and rearrange the checks in it.

cpuidle: pseries: Do not cap the CEDE0 latency in fixup_cede0_latency()
Currently in fixup_cede0_latency() code, we perform the fixup the CEDE(0) exit latency value only if minimum advertized extended CEDE latency values are less than 10us. This was done so as to not break the expected behaviour on POWER8 platforms where the advertised latency was higher than the default 10us, which would delay the SMT folding on the core. However, after the earlier patch "cpuidle/pseries: Fixup CEDE0 latency only for POWER10 onwards", we can be sure that the fixup of CEDE0 latency is going to happen only from POWER10 onwards. Hence unconditionally use the minimum exit latency provided by the platform. Signed-off-by: Gautham R.

cpuidle: teo: Rework most recent idle duration values treatment
The TEO (Timer Events Oriented) cpuidle governor uses several most
recent idle duration values for a given CPU to refine the idle state
selection in case the previous long-term trends have not been
followed recently and a new trend appears to be forming. That is
done by computing the average of the most recent idle duration
values falling below the time till the next timer event ("sleep
length"), provided that they are the majority of the most recent
idle duration values taken into account, and using it as the new
expected idle duration value.
However, idle state selection based on that value may not be optimal,
because the average does not really indicate which of the idle states
with target residencies less than or equal to it is likely to be the
best fit.
Thus, instead of computing the average, make the governor carry out
computations based on the distribution of the most recent idle
duration values among the bins corresponding to different idle
states. Namely, if the majority of the most recent idle duration
values taken into consideration are less than the current sleep
length (which means that the CPU is likely to wake up early), find
the idle state closest to the "candidate" one "matching" the sleep
length whose target residency is less than or equal to the majority
of the most recent idle duration values that have fallen below the
current sleep length (which means that it is likely to be "shallow
enough" this time).

cpuidle: teo: Change the main idle state selection logic
Two aspects of the current main idle state selection logic in the
TEO (Timer Events Oriented) cpuidle governor are quite questionable.
First of all, the "hits" and "misses" metrics used by it are only
updated for a given idle state if the time till the next timer event
("sleep length") is between the target residency of that state and
the target residency of the next one. Consequently, they are likely
to become stale if the sleep length tends to fall outside that
interval which increases the likelihood of subomtimal idle state
selection.
Second, the decision on whether or not to select the idle state
"matching" the sleep length is based on the metrics collected for
that state alone, whereas in principle the metrics collected for
the other idle states should be taken into consideration when that
decision is made. For example, if the measured idle duration is less
than the target residency of the idle state "matching" the sleep
length, then it is also less than the target residency of any deeper
idle state and that should be taken into account when considering
whether or not to select any of those states, but currently it is
not.
In order to address the above shortcomings, modify the main idle
state selection logic in the TEO governor to take the metrics
collected for all of the idle states into account when deciding
whether or not to select the one "matching" the sleep length.
Moreover, drop the "misses" metric that becomes redundant after the
above change and rename the "early_hits" metric to "intercepts" so
that its role is better reflected by its name (the idea being that
if a CPU wakes up earlier than indicated by the sleep length, then
it must be a result of a non-timer interrupt that "intercepts" the
CPU).
Also rename the states[] array in struct struct teo_cpu to
state_bins[] to avoid confusing it with the states[] array in
struct cpuidle_driver and update the documentation to match the
new code (and make it more comprehensive while at it).

If the time till the next timer event is shorter than the target residency of the first idle state (state 0), the TEO governor does not update its metrics for any idle states, but arguably it should record a "hit" for idle state 0 in that case, so modify it to do that. Accordingly, also make it record an "early hit" for idle state 0 if the measured idle duration is less than its target residency, which allows one branch more to be dropped from teo_update().

ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.
There is a trivial conflict in the cedrus driver, with two branches
adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
remove/remove conflict in linux/dma-mapping.h.

Merge tag 'arm-soc-drivers-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann:
"There are a couple of subsystems maintained by other people that merge
their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power
domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC
identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and
SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs"

cpuidle: psci: Enable suspend-to-idle for PSCI OSI mode
To select domain idlestates for cpuidle-psci when OSI mode has been enabled, the PM domains via genpd are being managed through runtime PM. This works fine for the regular idlepath, but it doesn't during system wide suspend. More precisely, the domain idlestates becomes temporarily disabled, which is because the PM core disables runtime PM for devices during system wide suspend. Later in the system suspend phase, genpd intends to deal with this from its ->suspend_noirq() callback, but this doesn't work as expected for a device corresponding to a CPU, because the domain idlestates needs to be selected on a per CPU basis (the PM core doesn't invoke the callbacks like that). To address this problem, let's enable the syscore flag for the corresponding CPU device that becomes successfully attached to its PM domain (applicable only in OSI mode). This informs the PM core to skip invoke the system wide suspend/resume callbacks for the device, thus also prevents genpd from screwing up its internal state of it. Moreover, to properly select a domain idlestate for the CPUs during suspend-to-idle, let's assign a specific ->enter_s2idle() callback for the corresponding domain idlestate (applicable only in OSI mode). From that callback, let's invoke dev_pm_genpd_suspend|resume(), as this allows a domain idlestate to be selected for the current CPU by genpd.

cpuidle: big.LITTLE: enable driver only on Peach-Pit/Pi Chromebooks
This driver always worked properly only on the Exynos 5420/5800 based Chromebooks (Peach-Pit/Pi), so change the required compatible string to the 'google,peach', to avoid enabling it on the other Exynos 542x/5800 boards, which hangs in such case. The main difference between Peach-Pit/Pi and other Exynos 542x/5800 boards is the firmware - Peach platform doesn't use secure firmware at all.

CPUs may fail to enter the chosen idle state if there was a pending interrupt, causing the cpuidle driver to return an error value. Record that and export it via sysfs along with the other idle state statistics.

cpuidle: psci: Allow PM domain to be initialized even if no OSI mode
If the PSCI OSI mode isn't supported or fails to be enabled, the PM domain topology with the genpd providers isn't initialized. This is perfectly fine from cpuidle-psci point of view. However, since the PM domain topology in the DTS files is a description of the HW, no matter of whether the PSCI OSI mode is supported or not, other consumers besides the CPUs may rely on it. Therefore, let's always allow the initialization of the PM domain topology to succeed, independently of whether the PSCI OSI mode is supported. Consequentially we need to track if we succeed to enable the OSI mode, as to know when a domain idlestate can be selected. Note that, CPU devices are still not being attached to the PM domain topology, unless the PSCI OSI mode is supported.

firmware: psci: Extend psci_set_osi_mode() to allow reset to PC mode
The current user (cpuidle-psci) of psci_set_osi_mode() only needs to enable the PSCI OSI mode. Although, as subsequent changes shows, there is a need to be able to reset back into the PSCI PC mode. Therefore, let's extend psci_set_osi_mode() to take a bool as in-parameter, to let the user indicate whether to enable OSI or to switch back to PC mode.
