The awcc_dmi_table[] uses DMI_MATCH() that supports partial matches. As
there is already "Alienware Area-51m" entry, "Alienware Area-51m R2" entry
is redundant.

The newer HP Omen laptops, such as Omen 16-wf1xxx, use the same
WMI-based thermal profile interface as Victus 16-r1000 and 16-s1000
models.
Add the DMI board name "8C78" to the victus_s_thermal_profile_boards
list to enable proper fan and thermal mode control.
Tested on: HP Omen 16-wf1xxx (board 8C78)
Result:
* Fan RPMs are readable
* echo 0 | sudo tee /sys/devices/platform/hp-wmi/hwmon/*/pwm1_enable
allows the fans to run on max RPM.

HONOR MagicBook X16/X14 models produced in 2025 cannot use the Print
Screen and YOYO keys properly, with the system reporting them as
unknown key presses (codes: 0x028b and 0x028e).
To resolve this, a key_entry is added for both the HONOR Print Screen

After studying the linuwu_sense driver
(https://github.com/0x7375646F/Linuwu-Sense) i was able to understand
the meaning of the SetGamingFanBehavior() WMI method:
- the first 16-bit are a bitmap of all fans affected by a fan behavior
change request.
- the next 8 bits contain four fan mode fields (2-bit), each being
associated with a bit inside the fan bitmap.
There are three fan modes: auto, turbo and custom.
Use this newfound knowledge to fix the turbo fan handling by setting
the correct bits before calling SetGamingFanBehavior(). Also check
the result of the WMI method call and return an error should the ACPI
firmware signal failure.

regulator_unregister() already frees the associated GPIO device. On
ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to
random failures when other drivers (typically Intel THC) attempt to
allocate interrupts. The root cause is that the reference count of the
pinctrl_intel_platform module unexpectedly drops to zero when this
driver defers its probe.
This behavior can also be reproduced by unloading the module directly.
Fix the issue by removing the redundant release of the GPIO device
during regulator unregistration.

During DT-binding review for extending the V4L2 camera sensor privacy LED
support to systems using devicetree, it has come up that having a "-led"
suffix for the LED name / con_id is undesirable since it already is clear
that it is a LED.
Drop the "-led" suffix from the con_id in both the lookup table in
the int3472 code, as well as from the con_id led_get() argument in
the v4l2-subdev code.

The amd_num_nodes() function returns the number of data fabrics present.
On older EPYC processors, there was one data fabric per socket.
However, newer EPYC processors have more than one data fabric per
socket, leading to a situation where the number of sockets is not equal
to the number of data fabrics. Therefore, it is appropriate to use
topology_max_packages() to know the number of sockets in the system.
Also remove node.h header inclusion and socket number comparison against
data fabric nodes.
plat.c is supported only for legacy platforms where socket number and
data fabric numbers are same. So it can remain unchanged.

./hfi.c:509:3-8: No need to set .owner here. The core will do it.
The manual assignment of .owner = THIS_MODULE; in the platform_driver
struct is redundant. The platform_driver_register() function, which is
called to register the driver, is a macro that automatically sets the
driver's owner to THIS_MODULE.
The driver core handles this assignment internally, making the explicit

Convert the PC Engines APUv2/v3 board driver to use software nodes
and static device properties for its on-board LEDs and front button.
This change replaces the legacy gpiod_lookup_table and platform_data
with a modern software node implementation, which allows the leds-gpio
and gpio-keys drivers to use the standard device properties API.

Convert the Meraki MX100 board driver to use software nodes and static
device properties to describe the on-board LEDs and reset button.
This moves away from the legacy gpiod_lookup_table and platform_data
mechanisms, allowing consumer drivers like leds-gpio and gpio-keys
to rely on the unified device properties interface instead of
board-specific data.

Since the x86-android-tablets code uses platform_create_bundle() it cannot
use EPROBE_DEFER and the driver-core will translate EPROBE_DEFER to ENXIO.
Stop using EPROBE_DEFER instead log an error and return ENODEV, or for
non-fatal cases log a warning and return 0.

2 fixes for Lenovo tablets:
- The bq24190 charger on the Lenovo Yoga Tab2 830/1050 devices does not use
the crystal-cove PMIC charger IRQ, so these shouldn't use bq24190_modules
as that includes "intel_crystal_cove_charger"
- Both the Tab2 and the Tab3 devices have a SPI audio-codec which init()
attaches properties to, resp. the whole SPI device gets instantiated by
the x86-android-tablets code. This requires the "spi_pxa2xx_platform"
module to be loaded before init() runs

lenovo_yoga_tab2_830_1050_exit() only gets called after a successful
lenovo_yoga_tab2_830_1050_init() call so there is no need to check
if lenovo_yoga_tab2_830_1050_codec_[dev|pinctrl] are set.
Also change the exit() order to be the exact reverse of init().

Add support for the Acer Iconia One 8 A1-840 (non FHD version) tablet.
This tablet has the usual issues for tablets shipped with Android as
factory OS. The DSDT is broken in various ways, so i2c_clients for
various devices as well as the INT3496 platform-device for OTG extcon
handling need to be instantiated manually by x86-android-tablets.
This tablet is special in that it is the first time a Bay Trail device
has been found to use the Dollar Cove TI PMIC and the first time that
the PMIC's Coulomb Counter is used as fuel-gauge.
So far this PMIC has only been used together with Cherry Trail SoCs
and always in combination with a separate full-featured fuel-gauge IC.

Acer has several x86 based Android tablets which need x86-android-tablets
support to work around their broken ACPI tables.
At the moment x86-android-tablets only support one model, move this to
its own file before adding support for more models to avoid needing to
move more code around later.

software_node_register_node_group() / software_node_unregister_node_group()
both accept a NULL node-group as argument.
So there is no need to check for the node-group being NULL before calling
these functions, remove the checks to simplify the code.
Note the "if (gpio_button_swnodes)" check for registering is kept because
that also guards the creation of a gpio-button platform-device.

Now that we are using software-nodes are used in more places it is
useful to have a more generic mechanism to have the core code register
software-nodes.
Replace the bat_swnode registration mechanism with a more generic
swnode_group registration mechanism.
