Add handling for events for the electronic privacy screen found on some
models (e.g. Dell Latitude 7300) being toggled on/off.
Emit KEY_EPRIVACY_SCREEN_OFF / KEY_EPRIVACY_SCREEN_ON events for this so
that userspace can show the usual on-screen-display (OSD) notification for
eprivacy screen on/off to the user.

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.

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.

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.

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

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 gpiolib supports software nodes to describe GPIOs, switch the

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for Goodix touchscreens to
using PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.
Since the tablets are using either Baytrail or Cherryview GPIO
controllers x86_dev_info structure has been extended to carry gpiochip
type information so that the code can instantiate correct set of
software nodes representing the GPIO chip.
Because this adds a new point of failure in x86_android_tablet_probe(),
x86_android_tablet_remove() is rearranged to handle cases where battery
swnode has not been registered yet, and registering of GPIO lookup
tables is moved earlier as it can not fail.

Replace dev_warn() with dev_dbg() to reduce unnecessary warning messages.
When the low power mode priority register contains invalid data, the Intel
PMC Core driver can still utilize the default priority list. This scenario
is more suited for debug information rather than warning.

When WMAB is called to set the fan mode, the new mode is read from either
bits 0-1 or bits 4-5 (depending on the value of some other EC register).
Thus when WMAB is called with bits 4-5 zeroed and called again with
bits 0-1 zeroed, the second call undoes the effect of the first call.
This causes writes to /sys/devices/platform/lg-laptop/fan_mode to have
no effect (and causes reads to always report a status of zero).
Fix this by calling WMAB once, with the mode set in bits 0,1 and 4,5.
When the fan mode is returned from WMAB it always has this form, so
there is no need to preserve the other bits. As a bonus, the driver
now supports the "Performance" fan mode seen in the LG-provided Windows
control app, which provides less aggressive CPU throttling but louder
fan noise and shorter battery life.
Also, correct the documentation to reflect that 0 corresponds to the
default mode (what the Windows app calls "Optimal") and 1 corresponds
to the silent mode.

After a reboot, if the user changes the thermal setting in the BIOS, the
BIOS applies this change. However, the current `dell-pc` driver does not
recognize the updated USTT value, resulting in inconsistent thermal
profiles between Windows and Linux.
To ensure alignment with Windows behavior, read the current USTT settings
during driver initialization and update the dell-pc USTT profile
accordingly whenever a change is detected.

This model was added as INTEL_PANTHERCOVE_X (based on the name of the
core) with a comment that the platform name is Diamond Rapids. It was
also placed at the end of the file in a new section for family 19
processors.
This is different from previous naming as Andrew Cooper noted.
PeterZ agreed and posted a patch[1] to fix the name and move it in
sequence with other Xeon servers. But without a commit description or
sign-off the patch wasn't ever applied.
Patch updated to cover one additional use of the #define by turbostat
and to change the "Family 6" comment to also list 18 and 19 since new
models in these families are mixed in with family 6.

It turns out that the dual screen models use 0x5E for attaching and
detaching the keyboard instead of 0x5F. So, re-add the codes by
reverting commit cf3940ac737d ("platform/x86: asus-wmi: Remove extra
keys from ignore_key_wlan quirk"). For our future reference, add a
comment next to 0x5E indicating that it is used for that purpose.
