buttons LED
The "input-events" LED trigger used to turn on the backlight LEDs had to
be rewritten to use led_trigger_register_simple() + led_trigger_event()
to fix a serious locking issue.
This means it no longer supports using blink_brightness to set a per LED
brightness for the trigger and it no longer sets LED_CORE_SUSPENDRESUME.
Adjust the MiPad 2 bottom bezel touch buttons LED class device to match:
1. Make LED_FULL the maximum brightness to fix the LED brightness
being very low when on.
2. Set flags = LED_CORE_SUSPENDRESUME.

Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future
Apart from the above, there are assorted thermal driver updates
Specifics:
- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki)
- Update the thermal sysfs code to store trip point attributes in
trip descriptors and get to trip points via attribute pointers
(Rafael Wysocki)
- Move the computation of the low and high boundaries for
thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
Lezcano)
- Introduce a debugfs-based facility for thermal core testing (Rafael
Wysocki)
- Replace the thermal zone .bind() and .unbind() callbacks for
binding cooling devices to thermal zones with one .should_bind()
callback used for deciding whether or not a given cooling devices
should be bound to a given trip point in a given thermal zone
(Rafael Wysocki)
- Eliminate code that has no more users after the other changes, drop
some redundant checks from the thermal core and clean it up (Rafael
Wysocki)
- Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)
- Refuse to accept trip point temperature or hysteresis that would
lead to an invalid threshold value when setting them via sysfs
(Rafael Wysocki)
- Adjust states of all uninitialized instances in the .manage()
callback of the Bang-bang thermal governor (Rafael Wysocki)
- Drop a couple of redundant checks along with the code depending on
them from the thermal core (Rafael Wysocki)
- Rearrange the thermal core to avoid redundant checks and simplify
control flow in a couple of code paths (Rafael Wysocki)
- Add power domain DT bindings for new Amlogic SoCs (Georges Stark)
- Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
driver and add a Kconfig dependency on THERMAL_OF subsystem for the
STi driver (Raphael Gallais-Pou)
- Simplify the error code path in the probe functions in the brcmstb
driver with the helo of dev_err_probe() (Yan Zhen)
- Make imx_sc_thermal use dev_err_probe() (Alexander Stein)
- Remove trailing space after \n newline in the Renesas driver (Colin
Ian King)
- Add DT binding compatible string for the SA8255p to the tsens
thermal driver (Nikunj Kela)
- Use the devm_clk_get_enabled() helpers to simplify the init routine
in the sprd thermal driver (Huan Yang)
- Remove __maybe_unused notations for the functions by using the new
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
Qoriq drivers (Fabio Estevam)
- Remove unused declarations from the ti-soc-thermal driver's header
file as the functions in question were removed previously (Zhang
Zekun)"

On some newer laptops ASUS laptops SPS support is advertised but not
actually used, causing the AMD driver to register as a platform_profile
handler.
If this happens then the asus_wmi driver would error with -EEXIST when
trying to register its own handler leaving the user with a possibly
unusable system. This is especially true for laptops with an MCU that emit
a stream of HID packets, some of which can be misinterpreted as shutdown
signals.
We can safely continue loading the driver instead of bombing out.

Add support to ignore all LTRs before suspend and restore the previous
LTR values after suspend. This feature could be turned off with module
parameter ltr_ignore_all_suspend.
LTR value is a mechanism for a device to indicate tolerance to access
the corresponding resource. When system suspends, the resource is not
available and therefore the LTR value could be ignored. Ignoring all
LTR values prevents problematic device from blocking the system to get
to the deepest package state during suspend.

The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

Allow to disable ACPI PM Timer on suspend and enable on resume. A
disabled timer helps optimise power consumption when the system is
suspended. On resume the timer is only reactivated if it was activated
prior to suspend, so unless the ACPI PM timer is enabled in the BIOS,
this won't change anything.
The ACPI PM timer is used by Intel's iTCO/wdat_wdt watchdog to drive the
watchdog, so it doesn't need to run during suspend.

First of all, it's a bit counterintuitive to have something like
int err;
...
scoped_guard(...)
err = foo(...);
if (err)
return err;
Second, with a particular kernel configuration and compiler version in
one of such cases the objtool is not happy:
ideapad-laptop.o: warning: objtool: .text.fan_mode_show: unexpected end of section
I'm not an expert on all this, but the theory is that compiler and
linker in this case can't understand that 'result' variable will be
always initialized as long as no error has been returned. Assigning
'result' to a dummy value helps with this. Note, that fixing the
scoped_guard() scope (as per above) does not make issue gone.
That said, assign dummy value and make the scope_guard() clear of its scope.
For the sake of consistency do it in the entire file.

The dell battery patch added dell_send_request_for_tokenid() and
dell_set_std_token_value(), which encapsulates a very common pattern
when SMBIOS queries are addressed to token->location. This calls them
in various places outside of the dell laptop code, allowing us to delete
a bunch of code.
Also some very minor cleanups:
- mark the kbd init functions as __init
- don't read buffer.output unless dell_send_request() was successful.
- actually return errors from micmute_led_set/mute_led_set instead of
always returning 0.
Only minor behavior changes; the delayed read of buffer.output and
actually returning errors for the brightness_set_blocking hooks.

The Dell BIOS allows you to set custom charging modes, which is useful
in particular for extending battery life. This adds support for tweaking
those various settings from Linux via sysfs knobs. One might, for
example, have their laptop plugged into power at their desk the vast
majority of the time and choose fairly aggressive battery-saving
settings (eg, only charging once the battery drops below 50% and only
charging up to 80%). When leaving for a trip, it would be more useful
to instead switch to a standard charging mode (top off at 100%, charge
any time power is available). Rebooting into the BIOS to change the
charging mode settings is a hassle.
For the Custom charging type mode, we reuse the common
charge_control_{start,end}_threshold sysfs power_supply entries. The
BIOS also has a bunch of other charging modes (with varying levels of
usefulness), so this also adds a 'charge_type' sysfs entry that maps the
standard values to Dell-specific ones.
This work is based on a patch by Perry Yuan <perry_yuan@dell.com> and
Limonciello Mario <Mario_Limonciello@Dell.com> submitted back in 2020.

In case of error in build_tokens_sysfs(), all the memory that has been
allocated is freed at end of this function. But then free_group() is
called which performs memory deallocation again.
Also, instead of free_group() call, there should be exit_dell_smbios_smm()
and exit_dell_smbios_wmi() calls, since there is initialization, but there
is no release of resources in case of an error.
Fix these issues by replacing free_group() call with
exit_dell_smbios_wmi() and exit_dell_smbios_smm().

Merge thermal core updates for 6.12 which, among other things, rework
the thermal driver interface for binding cooling devices to thermal
zones and add a thermal core testing module:
- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki).
- Update the thermal sysfs code to store trip point attributes in trip
descriptors and get to trip points via attribute pointers (Rafael
Wysocki).
- Move the computation of the low and high boundaries for
thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
Lezcano).
- Introduce a debugfs-based facility for thermal core testing (Rafael
Wysocki).
- Replace the thermal zone .bind() and .unbind() callbacks for binding
cooling devices to thermal zones with one .should_bind() callback
used for deciding whether or not a given cooling devices should be
bound to a given trip point in a given thermal zone (Rafael Wysocki).
- Eliminate code that has no more users after the other changes, drop
some redundant checks from the thermal core and clean it up (Rafael
Wysocki).
- Fix rounding of delay jiffies in the thermal core (Rafael Wysocki).

The scope of uncore control is per power domain with TPMI.
There are two types of processor topologies can be presented by CPUID
extended topology leaf irrespective of the hardware architecture:
1. A die is not enumerated in CPUID. In this case there is only one die
in a package is visible. In this case there can be multiple power domains
in a single die.
2. A power domain in a package is enumerated as a die in CPUID. So
there is one power domain per die.
To allow die level controls, the current implementation creates a root
domain and aggregates all information from power domains in it. This
is well suited for configuration 1 above.
But for configuration 2 above, the root domain will present the same
information as present by power domain. So, no use of aggregating. To
check the configuration, call topology_max_dies_per_package(). If it is
more than one, avoid creating root domain.

The Asus Zenbook Duo (UX8406MA) has a keyboard which can be
placed on the laptop to connect it via USB, or can be removed from the
laptop to reveal a hidden secondary display in which case the keyboard
operates via Bluetooth.
When it is placed on the secondary display to connect via USB, it emits
a keypress for a wireless disable. This causes the rfkill system to be
activated disconnecting the current wifi connection, which doesn't
reflect the user's true intention.
Detect this hardware and suppress any wireless switches from the
keyboard; this keyboard does not have a wireless toggle capability so
these presses are always spurious.

The commit 426463d94d45 ("platform/x86/amd/pmc: Send OS_HINT command for
new AMD platform") was introduced to enable sending mailbox commands to
PMFW on newer platforms. However, it was later discovered that the commit
did not configure the correct message port ID (i.e., S2D or PMC). Without
this configuration, all command submissions to PMFW are treated as
invalid, leading to command failures.
To address this issue, the CPU ID association for the new platform needs
to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU
port IDs are selected.

Make the acerhdf driver use the .should_bind() thermal zone
callback to provide the thermal core with the information on whether or
not to bind the given cooling device to the given trip point in the
given thermal zone. If it returns 'true', the thermal core will bind
the cooling device to the trip and the corresponding unbinding will be
taken care of automatically by the core on the removal of the involved
thermal zone or cooling device.
The previously existing acerhdf_bind() function bound cooling devices
to thermal trip point 0 only, so the new callback needs to return 'true'
for trip point 0. However, it is straightforward to observe that trip
point 0 is an active trip point and the only other trip point in the
driver's thermal zone is a critical one, so it is sufficient to return
'true' from that callback if the type of the given trip point is
THERMAL_TRIP_ACTIVE.

When only the last resource is invalid, tpmi_sst_dev_add() is returing
error even if there are other valid resources before. This function
should return error when there are no valid resources.
Here tpmi_sst_dev_add() is returning "ret" variable. But this "ret"
variable contains the failure status of last call to sst_main(), which
failed for the invalid resource. But there may be other valid resources
before the last entry.
To address this, do not update "ret" variable for sst_main() return
status.
If there are no valid resources, it is already checked for by !inst
below the loop and -ENODEV is returned.

The dell-uart-backlight driver supports backlight control on Dell All In
One (AIO) models using a backlight controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Now the first AIO has turned up which has not only the DSDT bits for this,
but also an actual controller attached to the UART, yet it is not using
this controller for backlight control.
Use the acpi_video_get_backlight_type() function from the ACPI video-detect
code to check if the dell-uart-backlight driver should actually be used.
This allows reusing the existing ACPI video-detect infra to override
the backlight control method on the commandline or with DMI quirks.
