46981fa784 ACPI: property: Fix error handling in acpi_init_properties()
buf.pointer, memory for storing _DSD data and nodes, was released if either
parsing properties or, as recently added, attaching data node tags failed.
Alas, properties were still left pointing to this memory if parsing
properties were successful but attaching data node tags failed.

Fix this by separating error handling for the two, and leaving properties
intact if data nodes cannot be tagged for a reason or another.

b0f2fe5a38 ACPI: VIOT: Do not dereference fwnode in struct device
In order to make the underneath API easier to change in the future,
prevent users from dereferencing fwnode from struct device.
Instead, use the specific dev_fwnode() and device_match_fwnode()
APIs for that.

1d239c1eb8 IOMMU Updates for Linux v5.20/v6.0:
Including:
 
 	- Most intrusive patch is small and changes the default
 	  allocation policy for DMA addresses. Before the change the
 	  allocator tried its best to find an address in the first 4GB.
 	  But that lead to performance problems when that space gets
 	  exhaused, and since most devices are capable of 64-bit DMA
 	  these days, we changed it to search in the full DMA-mask
 	  range from the beginning.  This change has the potential to
 	  uncover bugs elsewhere, in the kernel or the hardware. There
 	  is a Kconfig option and a command line option to restore the
 	  old behavior, but none of them is enabled by default.
 
 	- Add Robin Murphy as reviewer of IOMMU code and maintainer for
 	  the dma-iommu and iova code
 
 	- Chaning IOVA magazine size from 1032 to 1024 bytes to save
 	  memory
 
 	- Some core code cleanups and dead-code removal
 
 	- Support for ACPI IORT RMR node
 
 	- Support for multiple PCI domains in the AMD-Vi driver
 
 	- ARM SMMU changes from Will Deacon:
 
 	  - Add even more Qualcomm device-tree compatible strings
 
 	  - Support dumping of IMP DEF Qualcomm registers on TLB sync
 	    timeout
 
 	  - Fix reference count leak on device tree node in Qualcomm
 	    driver
 
 	- Intel VT-d driver updates from Lu Baolu:
 
 	  - Make intel-iommu.h private
 
 	  - Optimize the use of two locks
 
 	  - Extend the driver to support large-scale platforms
 
 	  - Cleanup some dead code
 
 	- MediaTek IOMMU refactoring and support for TTBR up to 35bit
 
 	- Basic support for Exynos SysMMU v7
 
 	- VirtIO IOMMU driver gets a map/unmap_pages() implementation
 
 	- Other smaller cleanups and fixes

668c3c237f sound updates for 6.0-rc1
As diffstat shows, we've had lots of developments in a wide range
 at this time; the majority of changes are about ASoC, including
 subsystem-wide cleanups, continued SOF / Intel updates and a
 bunch of new drivers (as usual), while there have been some
 significant (but almost invisible) improvements in ALSA core
 side, too.  Below are some highlights:
 
 Core:
 - Faster lookups of control elements with Xarray; normal user
   won't notice, but on the devices with tons of control elements,
   it can be visibly faster
 - Support for input validation for controls; this will harden
   for badly written drivers in general with a slight overhead
 - Deferred async signal handling for working around the potential
   deadlocks
 - Cleanup / refactoring raw MIDI locking code
 
 ASoC:
 - Restructing of the set_fmt() callbacks for making things clearer
   in situations like CODEC to CODEC links
 - Clean up and modernizing the DAI naming scheme setups
 - Merge of more of the Intel AVS driver stack, including some
   board integrations
 - New version 4 mechanism for communication with SOF DSPs
 - Suppoort for dynamically selecting the PLL to use at runtime on
   i.MX platforms
 - Improvements for CODEC to CODEC support in the generic cards
 - Support for AMD Jadeite and various machines, AMD RPL, Intel
   MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
   MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
   WAS883x, and Texas Instruments TAS2780
 
 HD- and USB-audio:
 - Continued improvement for CS35L41 (sub)codec support
 - More quirks for various devices (HP, Lenovo, Dell, Clevo)

Merge tag 'pci-v5.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate duplicated 'next function' scanning and extend to allow
     'isolated functions' on s390, similar to existing hypervisors
     (Niklas Schnelle)

  Resource management:
   - Implement pci_iobar_pfn() for sparc, which allows us to remove the
     sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().

     This removes the ability to map the entire PCI I/O space using
     /proc/bus/pci, but we believe that's already been broken since
     v2.6.28 (Arnd Bergmann)

   - Move common PCI definitions to asm-generic/pci.h and rework others
     to be be more specific and more encapsulated in arches that need
     them (Stafford Horne)

  Power management:

   - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
     CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)

  Virtualization:

   - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
     the functions but don't advertise an ACS capability (Pavan Chebbi)

  Error handling:

   - Clear PCI Status register during enumeration in case firmware left
     errors logged (Kai-Heng Feng)

   - When we have native control of AER, enable error reporting for all
     devices that support AER. Previously only a few drivers enabled
     this (Stefan Roese)

   - Keep AER error reporting enabled for switches. Previously we
     enabled this during enumeration but immediately disabled it (Stefan
     Roese)

   - Iterate over error counters instead of error strings to avoid
     printing junk in AER sysfs counters (Mohamed Khalfella)

  ASPM:

   - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
     via sysfs, are not lost across power state changes (Kai-Heng Feng)

  Endpoint framework:

   - Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)

  Endpoint embedded DMA controller driver:

   - Simplify and clean up support for the DesignWare embedded DMA
     (eDMA) controller (Frank Li, Serge Semin)

  Broadcom STB PCIe controller driver:

   - Avoid config space accesses when link is down because we can't
     recover from the CPU aborts these cause (Jim Quinlan)

   - Look for power regulators described under Root Ports in DT and
     enable them before scanning the secondary bus (Jim Quinlan)

   - Disable/enable regulators in suspend/resume (Jim Quinlan)

  Freescale i.MX6 PCIe controller driver:

   - Simplify and clean up clock and PHY management (Richard Zhu)

   - Disable/enable regulators in suspend/resume (Richard Zhu)

   - Set PCIE_DBI_RO_WR_EN before writing DBI registers (Richard Zhu)

   - Allow speeds faster than Gen2 (Richard Zhu)

   - Make link being down a non-fatal error so controller probe doesn't
     fail if there are no Endpoints connected (Richard Zhu)

  Loongson PCIe controller driver:

   - Add ACPI and MCFG support for Loongson LS7A (Huacai Chen)

   - Avoid config reads to non-existent LS2K/LS7A devices because a
     hardware defect causes machine hangs (Huacai Chen)

   - Work around LS7A integrated devices that report incorrect Interrupt
     Pin values (Jianmin Lv)

  Marvell Aardvark PCIe controller driver:

   - Add support for AER and Slot capability on emulated bridge (Pali
     Rohár)

  MediaTek PCIe controller driver:

   - Add Airoha EN7532 to DT binding (John Crispin)

   - Allow building of driver for ARCH_AIROHA (Felix Fietkau)

  MediaTek PCIe Gen3 controller driver:

   - Print decoded LTSSM state when the link doesn't come up (Jianjun
     Wang)

  NVIDIA Tegra194 PCIe controller driver:

   - Convert DT binding to json-schema (Vidya Sagar)

   - Add DT bindings and driver support for Tegra234 Root Port and
     Endpoint mode (Vidya Sagar)

   - Fix some Root Port interrupt handling issues (Vidya Sagar)

   - Set default Max Payload Size to 256 bytes (Vidya Sagar)

   - Fix Data Link Feature capability programming (Vidya Sagar)

   - Extend Endpoint mode support to devices beyond Controller-5 (Vidya
     Sagar)

  Qualcomm PCIe controller driver:

   - Rework clock, reset, PHY power-on ordering to avoid hangs and
     improve consistency (Robert Marko, Christian Marangi)

   - Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)

   - Add IPQ60xx support (Selvam Sathappan Periakaruppan)

   - Allow ASPM L1 and substates for 2.7.0 (Krishna chaitanya chundru)

   - Add support for more than 32 MSI interrupts (Dmitry Baryshkov)

  Renesas R-Car PCIe controller driver:

   - Convert DT binding to json-schema (Herve Codina)

   - Add Renesas RZ/N1D (R9A06G032) to rcar-gen2 DT binding and driver
     (Herve Codina)

  Samsung Exynos PCIe controller driver:

   - Fix phy-exynos-pcie driver so it follows the 'phy_init() before
     phy_power_on()' PHY programming model (Marek Szyprowski)

  Synopsys DesignWare PCIe controller driver:

   - Simplify and clean up the DWC core extensively (Serge Semin)

   - Fix an issue with programming the ATU for regions that cross a 4GB
     boundary (Serge Semin)

   - Enable the CDM check if 'snps,enable-cdm-check' exists; previously
     we skipped it if 'num-lanes' was absent (Serge Semin)

   - Allocate a 32-bit DMA-able page to be MSI target instead of using a
     driver data structure that may not be addressable with 32-bit
     address (Will McVicker)

cfeafd9466 Driver core / kernfs changes for 6.0-rc1
Here is the set of driver core and kernfs changes for 6.0-rc1.
 
 "biggest" thing in here is some scalability improvements for kernfs for
 large systems.  Other than that, included in here are:
 	- arch topology and cache info changes that have been reviewed
 	  and discussed a lot.
 	- potential error path cleanup fixes
 	- deferred driver probe cleanups
 	- firmware loader cleanups and tweaks
 	- documentation updates
 	- other small things
 
 All of these have been in the linux-next tree for a while with no
 reported problems.

7d9d077c78 RCU pull request for v5.20 (or whatever)
This pull request contains the following branches:
 
 doc.2022.06.21a: Documentation updates.
 
 fixes.2022.07.19a: Miscellaneous fixes.
 
 nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new
 	RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to
 	be offloaded at boot time, regardless of kernel boot parameters.
 	This is useful to battery-powered systems such as ChromeOS
 	and Android.  In addition, a new RCU_NOCB_CPU_CB_BOOST kernel
 	boot parameter prevents offloaded callbacks from interfering
 	with real-time workloads and with energy-efficiency mechanisms.
 
 poll.2022.07.21a: Polled grace-period updates, perhaps most notably
 	making these APIs account for both normal and expedited grace
 	periods.
 
 rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing
 	the CPU overhead of RCU tasks trace grace periods by more than
 	a factor of two on a system with 15,000 tasks.	The reduction
 	is expected to increase with the number of tasks, so it seems
 	reasonable to hypothesize that a system with 150,000 tasks might
 	see a 20-fold reduction in CPU overhead.
 
 torture.2022.06.21a: Torture-test updates.
 
 ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into
 	context tracking, thus reducing the overhead of transitioning to
 	kernel mode from either idle or nohz_full userspace execution
 	for kernels that track context independently of RCU.  This is
 	expected to be helpful primarily for kernels built with
 	CONFIG_NO_HZ_FULL=y.

4f4179fcf4 ACPI: CPPC: Do not prevent CPPC from working in the future
There is a problem with the current revision checks in
is_cppc_supported() that they essentially prevent the CPPC support
from working if a new _CPC package format revision being a proper
superset of the v3 and only causing _CPC to return a package with more
entries (while retaining the types and meaning of the entries defined by
the v3) is introduced in the future and used by the platform firmware.

In that case, as long as the number of entries in the _CPC return
package is at least CPPC_V3_NUM_ENT, it should be perfectly fine to
use the v3 support code and disregard the additional package entries
added by the new package format revision.

For this reason, drop is_cppc_supported() altogether, put the revision
checks directly into acpi_cppc_processor_probe() so they are easier to
follow and rework them to take the case mentioned above into account.

ec6c050319 ACPI: PM: x86: Print messages regarding LPS0 idle support
Because suspend-to-idle is always supported and on x86 it is the only
way to suspend the system if S3 is not supported by the platform, the
kernel attempts to enter low-power S0 idle in the suspend-to-idle flow
regardless of whether or not the ACPI_FADT_LOW_POWER_S0 flag is set in
the FADT.  However, if that flag is not set, residency counters
associated with low-power S0 idle may not count and the platform may
refuse to put the EC into a low-power mode, for example.

For this reason, print diagnostic messages when the platform should
achieve significant energy savings in low-power S0 idle (because the
ACPI_FADT_LOW_POWER_S0 flag is set in the FADT) and when
suspend-to-idle becomes the default suspend method (because low-power
S0 idle should be equally or more efficient than S3, if available).

0c80f9e165 ACPI: PPTT: Leave the table mapped for the runtime usage
Currently, everytime an information needs to be fetched from the PPTT,
the table is mapped via acpi_get_table() and unmapped after the use via
acpi_put_table() which is fine. However we do this at runtime especially
when the CPU is hotplugged out and plugged in back since we re-populate
the cache topology and other information.

However, with the support to fetch LLC information from the PPTT in the
cpuhotplug path which is executed in the atomic context, it is preferred
to avoid mapping and unmapping of the PPTT for every single use as the
acpi_get_table() might sleep waiting for a mutex.

In order to avoid the same, the table is needs to just mapped once on
the boot CPU and is never unmapped allowing it to be used at runtime
with out the hassle of mapping and unmapping the table.

9946e39fe8 ACPI: resource: skip IRQ override on AMD Zen platforms
IRQ override isn't needed on modern AMD Zen systems.
There's an active low keyboard IRQ on AMD Ryzen 6000 and it will stay
this way on newer platforms. This IRQ override breaks keyboards for
almost all Ryzen 6000 laptops currently on the market.

Skip this IRQ override for all AMD Zen platforms because this IRQ
override is supposed to be a workaround for buggy ACPI DSDT and we can't
have a long list of all future AMD CPUs/Laptops in the kernel code.
If a device with buggy ACPI DSDT shows up, a separated list containing
just them should be created.

744b9a0c3c ACPI: irq: Allow acpi_gsi_to_irq() to have an arch-specific fallback
It appears that the generic version of acpi_gsi_to_irq() doesn't
fallback to establishing a mapping if there is no pre-existing
one while the x86 version does.

While arm64 seems unaffected by it, LoongArch is relying on the x86
behaviour. In an effort to prevent new architectures from reinventing
the proverbial wheel, provide an optional callback that the arch code
can set to restore the x86 behaviour.

Hopefully we can eventually get rid of this in the future once
the expected behaviour has been clarified.

7327b16f5f APCI: irq: Add support for multiple GSI domains
In an unfortunate departure from the ACPI spec, the LoongArch
architecture split its GSI space across multiple interrupt
controllers.

In order to be able to reuse the core code and prevent
architectures from reinventing an already square wheel, offer
the arch code the ability to register a dispatcher function
that will return the domain fwnode for a given GSI.

The ARM GIC drivers are updated to support this (with a single
domain, as intended).

09073396ea ACPI: CPPC: Don't require flexible address space if X86_FEATURE_CPPC is supported
Commit 0651ab90e4 ("ACPI: CPPC: Check _OSC for flexible address space")
changed _CPC probing to require flexible address space to be negotiated
for CPPC to work.

However it was observed that this caused a regression for Arek's ROG
Zephyrus G15 GA503QM which previously CPPC worked, but now it stopped
working.

To avoid causing a regression waive this failure when the CPU is known
to support CPPC.

03c440a26c ACPI: video: Use native backlight on Dell Inspiron N4010
The Dell Inspiron N4010 does not have ACPI backlight control,
so acpi_video_get_backlight_type()'s heuristics return vendor as
the type to use.

But the vendor interface is broken, where as the native (intel_backlight)
works well, add a quirk to use native.

1a2dcab517 ACPI: PM: s2idle: Use LPS0 idle if ACPI_FADT_LOW_POWER_S0 is unset
If the PNP0D80 device is present and its _DSM appears to be valid,
there is no reason to avoid using it even if ACPI_FADT_LOW_POWER_S0
is unset in the FADT, because suspend-to-idle may be the only way to
suspend the system if S3 is not supported by the platform, so do not
return early from lps0_device_attach() in that case.

However, still check ACPI_FADT_LOW_POWER_S0 when deciding whether or
not suspend-to-idle should be the default system suspend method.

Revert commit 1cdda9486f ("ACPI / PM: LPIT: Register sysfs attributes
based on FADT"), because what it did was more confusing than it would
be to allow the sysfs attributes in question to be created regardless
of whether or not the relevant flag was set in the FADT.

If ACPI_FADT_LOW_POWER_S0 is not set, it need not mean that LPIT is
invalid and low-power S0 idle is not usable.  It merely means that
using S3 on the given system is more beneficial from the energy
saving perspective than using low-power S0 idle.

Loongson PCH (LS7A chipset) will be used by both MIPS-based and LoongArch-
based Loongson processors. MIPS-based Loongson uses FDT, while LoongArch-
based Loongson uses ACPI.

Add ACPI init support for the driver in pci-loongson.c because it is
currently FDT-only.

LoongArch is a new RISC ISA, mainline support will come soon, and
documentations are here (in translation):

5ad26161a3 ACPI: video: Fix acpi_video_handles_brightness_key_presses()
Commit 3a0cf7ab8d ("ACPI: video: Change how we determine if brightness
key-presses are handled") made acpi_video_handles_brightness_key_presses()
report false when none of the ACPI Video Devices support backlight control.

But it turns out that at least on a Dell Inspiron N4010 there is no ACPI
backlight control, yet brightness hotkeys are still reported through
the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses()
now returns false, brightness keypresses are now reported twice.

To fix this rename the has_backlight flag to may_report_brightness_keys and
also set it the first time a brightness key press event is received.

Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video
Bus event this means that the first brightness key press might still get
reported twice, but all further keypresses will be filtered as before.

Note that this relies on other drivers reporting brightness key events
calling acpi_video_handles_brightness_key_presses() when delivering
the events (rather then once during driver probe). This is already
required and documented in include/acpi/video.h:

/*
 * Note: The value returned by acpi_video_handles_brightness_key_presses()
 * may change over time and should not be cached.
 */

Taking a recent change in the i8042 quirklist to this one: Clevo
board_names are somewhat unique, and if not: The generic Board_-/Sys_Vendor
string "Notebook" doesn't help much anyway. So identifying the devices just
by the board_name helps keeping the list significantly shorter and might
even hit more devices requiring the fix.

c752089f7c ACPI: video: Force backlight native for some TongFang devices
The TongFang PF5PU1G, PF4NU1F, PF5NU1G, and PF5LUXG/TUXEDO BA15 Gen10,
Pulse 14/15 Gen1, and Pulse 15 Gen2 have the same problem as the Clevo
NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2:
They have a working native and video interface. However the default
detection mechanism first registers the video interface before
unregistering it again and switching to the native interface during boot.
This results in a dangling SBIOS request for backlight change for some
reason, causing the backlight to switch to ~2% once per boot on the first
power cord connect or disconnect event. Setting the native interface
explicitly circumvents this buggy behaviour by avoiding the unregistering
process.
