There have been 2 separate reports now about a non working
"dell_backlight" device getting registered under /sys/class/backlight
1 report for a Raptor Lake based Dell and 1 report for a Meteor Lake
(development) platform.
On hw from the last 10 years dell-laptop will not register "dell_backlight"
because acpi_video_get_backlight_type() will return acpi_backlight_video
there if called before the GPU/kms driver loads. So it does not matter if
the GPU driver's native backlight is registered after dell-laptop loads.
But it seems that on the latest generation laptops the ACPI tables
no longer contain acpi_video backlight control support which causes
acpi_video_get_backlight_type() to return acpi_backlight_vendor causing
"dell_backlight" to get registered if the dell-laptop module is loaded
before the GPU/kms driver.
Vendor specific backlight control like the "dell_backlight" device is
only necessary on quite old hw (from before acpi_video backlight control
was introduced). Work around "dell_backlight" registering on very new
hw (where acpi_video backlight control seems to be no more) by making
acpi_video_get_backlight_type() return acpi_backlight_none instead
of acpi_backlight_vendor as final fallback when the ACPI tables have
support for Windows 8 or later (laptops from after ~2012).

In Windows the Microsoft _DSM doesn't call functions 3->5->7 for suspend

Rather it calls 3->7->5 for suspend and 6->8->4 for resume.
Align this calling order for Linux as well.

commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on
AMD Zen platforms") attempted to overhaul the override logic so it
didn't apply on X86 AMD Zen systems. This was intentional so that
systems would prefer DSDT values instead of default MADT value for
IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1.
This turned out to be a bad assumption because several vendors
add Interrupt Source Override but don't fix the DSDT. A pile of
quirks was collecting that proved this wasn't sustaintable.
Furthermore some vendors have used ActiveHigh for IRQ1.
To solve this problem revert the following commits:
* commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang
GMxRGxx")
* commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7")
* commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
* commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15")

The acpi_sleep_suspend_setup() function is missing an __init annotation,
which causes a warning in rare configurations that end up not inlining
it into its caller:
WARNING: modpost: vmlinux.o: section mismatch in reference: acpi_sleep_suspend_setup (section: .text) -> acpi_s2idle_setup (section: .init.text)
It's only called from an __init function, so adding the annotation is
correct here.

The nfit_intel_shutdown_status() function has a __weak defintion
in nfit.c and an override in acpi_nfit_test.c for testing
purposes. This works without an extern declaration, but causes
a W=1 build warning:

Notice that all of the objects for which the acpi_scan_check_dep()
return value is greater than 0 are present in acpi_dep_list as consumers
(there may be multiple entries for one object, but that is not a
problem), so after carrying out the initial ACPI namespace walk in which
devices with dependencies are skipped, acpi_bus_scan() can simply walk
acpi_dep_list and enumerate all of the unique consumer objects from
there and their descendants instead of walking the entire target branch
of the ACPI namespace and looking for device objects that have not been
enumerated yet in it.
Because walking acpi_dep_list is generally less overhead than walking
the entire ACPI namespace, use the observation above to reduce the
system initialization overhead related to ACPI, which is particularly
important on large systems.

BSW PWM2 is used for backlight control for fixed (etched into the glass)
touch controls on some models.
Add an entry for the second PWM controller to bsw_pwm_lookup,
so that drivers can use pwm_get() to get a reference to it.
These touch-controls have specialized drivers which bind to different
devices on different models, so the consumer-device-name in the lookup
table entry is set to NULL, so that only con-id matching is used.
The con-id is set to "pwm_soc_lpss_2" which describes the PWM controller
rather than the usual approach of describing its function.
The specialized (model specific) drivers which need access to the PWM
controller know they need the "pwm_soc_lpss_2" con-id.

The Lenovo Yoga Book yb1-x90f/l 2-in-1 which ships with Android as
Factory OS has (another) bug in its DSDT where the UART resource for
the BTH0 ACPI device contains "\\_SB.PCIO.URT1" as path to the UART.
Note that is with a letter 'O' instead of the number '0' which is wrong.
This causes Linux to instantiate a standard /dev/ttyS? device for
the UART instead of a /sys/bus/serial device, which in turn causes
bluetooth to not work.
Similar DSDT bugs have been encountered before and to work around those
the acpi_quirk_skip_serdev_enumeration() helper exists.
Previous devices had the broken resource pointing to the first UART, while
the BT HCI was on the second UART, which ACPI_QUIRK_UART1_TTY_UART2_SKIP
deals with. Add a new ACPI_QUIRK_UART1_SKIP quirk for skipping enumeration
of UART1 instead for the Yoga Book case and add this quirk to the
existing DMI quirk table entry for the yb1-x90f/l .
This leaves the UART1 controller unbound allowing the x86-android-tablets
module to manually instantiate a serdev for it fixing bluetooth.

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86
as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there (the Android x86 kernel fork ignores I2C devices described
in the DSDT).
On this specific model this just not cause resource conflicts, one of
the probe() calls for the non existing i2c_clients actually ends up
toggling a GPIO or executing a _PS3 after a failed probe which turns
the tablet off.
Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the
acpi_quirk_skip_dmi_ids table to avoid the bogus i2c_clients and
to fix the tablet turning off during boot because of this.
Also add the "10EC5651" HID for the RealTek ALC5651 codec used
in this tablet to the list of HIDs for which not to skipi2c_client
instantiation, since the Intel SST sound driver relies on
the codec being instantiated through ACPI.

Remove the acpi_backlight=video quirk for Lenovo ThinkPad W530.
This was intended to help users of the (unsupported) Nvidia binary driver,
but this has been reported to cause backlight control issues for users
who have the gfx configured in hybrid (dual-GPU) mode, so drop this.
The Nvidia binary driver should call acpi_video_register_backlight()
when necessary and this has been reported to Nvidia.
Until this is fixed Nvidia binary driver users can work around this by
passing "acpi_backlight=video" on the kernel commandline (with the latest
6.1.y or newer stable series, kernels < 6.1.y don't need this).

The ACPI thermal driver creates extra sysfs attributes in its own
directory pointing to the thermal zone it is related to and add a
pointer to the sysfs ACPI thermal device from the thermal zone sysfs
entry.
This is very specific to this ACPI thermal driver, let's encapsulate
the related creation/deletion code to group it inside a function we
can identify later for removal if needed.

In order to get the device associated with the thermal zone, let's use
the wrapper thermal_zone_device() instead of accessing directly the
content of the thermal zone device structure.

The Wi-Fi module in x86 Apple machines has a "module-instance" device
property that specifies the platform type and is used for firmware
selection. Its value is a string, so add support for string values in
acpi_extract_apple_properties().

The LSM303D on the Lenovo Yoga Tablet 2 series is present
as both ACCL0001 and MAGN0001. As we can only ever register an
i2c client for one of them, ignore MAGN0001.
Currently this errors:

The CPR3 power resource on the Toshiba Click Mini toggles a GPIO
which is called SISP (for SIS touchscreen power?) on/off.
This CPR3 power resource is not listed in any _PR? lists, let alone
in a _PR0 list for the SIS0817 touchscreen ACPI device which needs it.
Before commit a1224f34d72a ("ACPI: PM: Check states of power resources
during initialization") this was not an issue because since nothing
referenced the CPR3 power resource its state was always
ACPI_POWER_RESOURCE_STATE_UNKNOWN and power resources with this state
get ignored by acpi_turn_off_unused_power_resources().
This clearly is a bug in the DSDT of this device. Add a DMI quirk
to make acpi_turn_off_unused_power_resources() a no-op on this
model to fix the touchscreen no longer working since kernel 5.16 .
This quirk also causes 2 other power resources to not get turned
off, but the _OFF method on these already was a no-op, so this makes
no difference for the other 2 power resources.
Fixes: a1224f34d72a ("ACPI: PM: Check states of power resources during initialization")

Pull arm64 updates from Will Deacon:
"ACPI:
- Improve error reporting when failing to manage SDEI on AGDI device
removal
Assembly routines:
- Improve register constraints so that the compiler can make use of
the zero register instead of moving an immediate #0 into a GPR
- Allow the compiler to allocate the registers used for CAS
instructions
CPU features and system registers:
- Cleanups to the way in which CPU features are identified from the
ID register fields
- Extend system register definition generation to handle Enum types
when defining shared register fields
- Generate definitions for new _EL2 registers and add new fields for
ID_AA64PFR1_EL1
- Allow SVE to be disabled separately from SME on the kernel
command-line
Tracing:
- Support for "direct calls" in ftrace, which enables BPF tracing for
arm64
Kdump:
- Don't bother unmapping the crashkernel from the linear mapping,
which then allows us to use huge (block) mappings and reduce TLB
pressure when a crashkernel is loaded.
Memory management:
- Try again to remove data cache invalidation from the coherent DMA
allocation path
- Simplify the fixmap code by mapping at page granularity
- Allow the kfence pool to be allocated early, preventing the rest of
the linear mapping from being forced to page granularity
Perf and PMU:
- Move CPU PMU code out to drivers/perf/ where it can be reused by
the 32-bit ARM architecture when running on ARMv8 CPUs
- Fix race between CPU PMU probing and pKVM host de-privilege
- Add support for Apple M2 CPU PMU
- Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
dynamically, depending on what the CPU actually supports
- Minor fixes and cleanups to system PMU drivers
Stack tracing:
- Use the XPACLRI instruction to strip PAC from pointers, rather than
rolling our own function in C
- Remove redundant PAC removal for toolchains that handle this in
their builtins
- Make backtracing more resilient in the face of instrumentation
Miscellaneous:
- Fix single-step with KGDB
- Remove harmless warning when 'nokaslr' is passed on the kernel

- Fix evaluating the _PDC ACPI control method when running as Xen
dom0 (Roger Pau Monne).
- Use platform devices to load ACPI PPC and PCC drivers (Petr Pavlu).
- Check for null return of devm_kzalloc() in fch_misc_setup() (Kang
Chen).

This reverts commit 5c62d5aab8752e5ee7bfbe75ed6060db1c787f98.
This broke wake-on-lan for multiple people, and for much too long.

On some Cherry Trail devices the second PWM controller uses
80862289 as ACPI _HID, rather then using 80862288 as is done
for both controllers on most models.
Add the missing 80862289 ACPI _HID, note this uses its own
lpss_device_desc, without ".setup = bsw_pwm_setup" so that
the pwm_lookup is not added for it.
On devices where both controllers use the 80862288 _HID bsw_pwm_setup()
does a UID check to avoid registering the lookup for the second
controller but that will not work here.
Adding the missing id fixes the second PWM controller no longer
working after the entire LPSS1 island has been in D3 at least
once, which causes the contents of the LPSS private registers
to get lost. Adding the _HID makes acpi_lpss restore these
when the controller moves from D3 to D0.

Currently, acpi_device_remove_notify_handler() may return while the
notify handler being removed is still running which may allow the
module holding that handler to be torn down prematurely.
Address this issue by making acpi_device_remove_notify_handler() wait
for the handling of all the ACPI events in progress to complete before
returning.

Returning an error value in a platform driver's remove callback results in
a generic error message being emitted by the driver core, but otherwise it
doesn't make a difference. The device goes away anyhow.
So instead of triggering the generic platform error message, emit a more
helpful message if a problem occurs and return 0 to suppress the generic
message.
This patch is a preparation for making platform remove callbacks return
void.
