As the atomisp driver should already be handling the ISP
PCI ID, there's no sense on keeping the dummy driver enabled
in tis case.

f441d66a6e platform/x86: dell-wmi: Ignore keyboard attached / detached events
Ignore events with a type of 0x0011 and a code of 0xfff2 / 0xfff3,
this silences the following messages being logged when the keyboard is
detached / attached on a Dell Venue 11 Pro 7130:

[   63.621953] dell_wmi: Unknown key with type 0x0011 and code 0xfff2 pressed
[   70.240558] dell_wmi: Unknown key with type 0x0011 and code 0xfff3 pressed

Note SW_TABLET_MODE is already reported through the intel_vbtn driver on
this and other Dell devices, so dell_wmi should not report this too,
to avoid duplicate events.

257e03a334 platform/x86: dell-laptop: don't register micmute LED if there is no token
On Dell G3-3590, error message is issued during boot up,
"platform::micmute: Setting an LED's brightness failed (-19)",
but there's no micmute led on the machine.

Get the related tokens of SMBIOS, GLOBAL_MIC_MUTE_DISABLE/ENABLE.
If one of two tokens doesn't exist,
don't call led_classdev_register() for platform::micmute.
After that, you wouldn't see the platform::micmute in /sys/class/leds/,
and the error message wouldn't see in dmesg.

dd950f16b1 platform/x86: intel-vbtn: Detect switch position before registering the input-device
Setting the initial state of input-device switches must be done before
registering the input-device.

Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.

E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):

E: 0.000001 0005 0005 0001	# EV_SW / SW_DOCK              1
E: 0.000001 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000	# EV_SW / SW_DOCK              0
E: 0.000109 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000133 0005 0001 0001	# EV_SW / SW_TABLET_MODE       1
E: 0.000133 0000 0000 0000	# ------------ SYN_REPORT (0) ---------- +0ms

The first SW_DOCK=1 report is spurious, setting the initial switch
state before registering the input-device fixes this.

10d7ff74b6 platform/x86: asus-wmi: Ignore WMI events with code 0x79
On some Asus devices, e.g. the T100TA, when the charger is connected
we not only get a WMI event with code 0x58, but immediately after that
event we also get an even with code 0x79.

This is likely related to these devices having an Asus WMI device with a
device-id of 0x00120066, which seems to provide some sort of charger-type
info. The T100TA charger over a micro-USB connector, the embedded-
controller register read when calling asus_wmi_get_devstate(0x00120066)
returns different values when connected to a USB port (max 500mA charging)
vs when connected to a 2A capable wall-charger. But the AML code reading
this mangles the return value so that we can no longer tell the difference.
So for now the meaning of the value return when getting the status of
device-id 0x00120066 is unclear.

This commit adds a key-mapping of code 0x79 to KE_IGNORE, silencing the
kernel logging the following message every time the charger is plugged-in:

[   79.639548] asus_wmi: Unknown key 79 pressed

aab9e7896e platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"
The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.

To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.

Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode.

Note, not calling INIT is also not an option, because then we will not
receive events when the tablet-mode changes. So the LED issue will need
to be fixed somewhere else entirely.

47828d2253 platform/x86: sony-laptop: SNC calls should handle BUFFER types
After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer
objects for ASL create_field() operator") ACPICA creates buffers even
when new fields are small enough to fit into an integer.
Many SNC calls counted on the old behaviour.
Since sony-laptop already handles the INTEGER/BUFFER case in
sony_nc_buffer_call, switch sony_nc_int_call to use its more generic
function instead.

d307f17293 platform/x86: intel-vbtn: Fix probe failure on devices with only switches
On some devices the INT33D6 vbtn device is only used to report
tablet-mode / docked status (switches) and there are no vbtn managed
buttons.

On these devices there is no VBDL object.

Move the VBDL check to a intel_vbtn_has_buttons() helper and only exit
from intel_vbtn_probe() with -ENODEV when there are both no buttons and
no switches. Also only report the buttons being present to userspace if
the has_buttons check has succeeded.

1fac39fd03 platform/x86: intel-vbtn: Also handle tablet-mode switch on "Detachable" and "Portable" chassis-types
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally
reporting SW_TABLET_MODE = 1 to userspace on laptops.

Some devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report if they are in tablet mode (keyboard detached) or not,
report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series.

Other devices with a detachable keyboard and using the intel-vbnt (INT33D6)
interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type.
The Dell Venue 11 Pro 7130 is an example of this.

Extend the DMI chassis-type check to also accept Portables and Detachables
so that the intel-vbtn driver will report SW_TABLET_MODE on these devices.

Note the chassis-type check was originally added to avoid a false-positive
tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge
that laptop is using a chassis-type of 9 / "Laptop", so after this commit
we still ignore the tablet-switch for that chassis-type.

990fbb4806 platform/x86: intel-vbtn: Do not advertise switches to userspace if they are not there
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a DMI chassis-type check to avoid accidentally
reporting SW_TABLET_MODE = 1 to userspace on laptops (specifically on the
Dell XPS 9360), to avoid e.g. userspace ignoring touchpad events because
userspace thought the device was in tablet-mode.

But if we are not getting the initial status of the switch because the
device does not have a tablet mode, then we really should not advertise
the presence of a tablet-mode switch to userspace at all, as userspace may
use the mere presence of this switch for certain heuristics.

2d30fcdd43 platform/x86: Add Slim Bootloader firmware update signaling driver
Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.

Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.

SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:

echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request

This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

3ce2db608e platform/x86: intel_pmc_core: avoid unused-function warnings
When both CONFIG_DEBUG_FS and CONFIG_PM_SLEEP are disabled, the
functions that got moved out of the #ifdef section now cause
a warning:

drivers/platform/x86/intel_pmc_core.c:654:13: error: 'pmc_core_lpm_display' defined but not used [-Werror=unused-function]
  654 | static void pmc_core_lpm_display(struct pmc_dev *pmcdev, struct device *dev,

drivers/platform/x86/intel_pmc_core.c:617:13: error: 'pmc_core_slps0_display' defined but not used [-Werror=unused-function]
  617 | static void pmc_core_slps0_display(struct pmc_dev *pmcdev, struct device *dev,
      |             ^~~~~~~~~~~~~~~~~~~~~~

Rather than add even more #ifdefs here, remove them entirely and
let the compiler work it out, it can actually get rid of all the
debugfs calls without problems as long as the struct member is
there.

The two PM functions just need a __maybe_unused annotations to avoid
another warning instead of the #ifdef.

3bd12da7f5 platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA
asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.

Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.

This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

14232c6e78 platform/x86: thinkpad_acpi: Add support for dual fan control
This adds dual fan control for the following models:
P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.

Both fans are controlled together as if they were a single fan.

Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.

The patch is defensive, it adds only specific supported machines, and falls
back to the old behavior if both fans cannot be controlled.

Background:
I tested the BIOS default behavior on my X1E gen2 and both fans are always
changed together. So rather than adding controls for each fan, this controls
both fans together as the BIOS would do.

This was inspired by a discussion on dual fan support for the thinkfan tool
(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
verified on my machine.

Thanks to GitHub users voidworker and civic9 for the earlier patches and
BIOS IDs, and to users peter-stoll and sassman for testing the patch on
their machines.

25f1ca31e2 platform/x86: intel_pmc_ipc: Convert to MFD
This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.

MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.

The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.
