thinkpad_acpi was reporting 2 fans on a ThinkPad T14s gen 1, even though
the laptop has only 1 fan.
The second, not present fan always reads 65535 (-1 in 16 bit signed),
ignore fans which report 65535 to avoid reporting the non present fan.

It was observed that on a Thinkpad T14 Gen1 (AMD) that the platform
profile is starting up in 'low-power' mode after refreshing what the
firmware had. This is most likely a firmware bug, but as a harmless
workaround set the default profile to 'balanced' at thinkpad_acpi startup.

Instead of walking the list of children of an ACPI device directly,
use acpi_dev_for_each_child() to carry out an action for all of
the given ACPI device's children.
This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).

Lenovo laptops that contain NVME SSDs across a variety of generations have
trouble resuming from suspend to idle when the IOMMU translation layer is
active for the NVME storage device.
This generally manifests as a large resume delay or page faults. These
delays and page faults occur as a result of a Lenovo BIOS specific SMI
that runs during the D3->D0 transition on NVME devices.
This SMI occurs because of a flag that is set during resume by Lenovo
firmware:
```
OperationRegion (PM80, SystemMemory, 0xFED80380, 0x10)
Field (PM80, AnyAcc, NoLock, Preserve)
{
SI3R, 1
}
Method (_ON, 0, NotSerialized) // _ON_: Power On
{
TPST (0x60D0)
If ((DAS3 == 0x00))
{
If (SI3R)
{
TPST (0x60E0)
M020 (NBRI, 0x00, 0x00, 0x04, (NCMD | 0x06))
M020 (NBRI, 0x00, 0x00, 0x10, NBAR)
APMC = HDSI /* \HDSI */
SLPS = 0x01
SI3R = 0x00
TPST (0x60E1)
}
D0NV = 0x01
}
}
```
Create a quirk that will run early in the resume process to prevent this
SMI from running. As any of these machines are fixed, they can be peeled
back from this quirk or narrowed down to individual firmware versions.

Instead of having quirks for systems that have a second fan it would
be nice to detect this setup.
Unfortunately, confirmed by the Lenovo FW team, there is no way to
retrieve this information from the EC or BIOS. Recommendation was to
attempt to read the fan and if successful then assume a 2nd fan is
present.
The fans are also supposed to spin up on boot for some time, so in
theory we could check for a speed > 0. In testing this seems to hold
true but as I couldn't test on all platforms I've avoided implementing
this. It also breaks for the corner case where you load the module
once the fans are idle.
Tested on P1G4, P1G3, X1C9 and T14 (no fans) and it works correctly.
For the platforms with dual fans where it was confirmed to work I have
removed the quirks. Potentially this could be done for all platforms
but I've left untested platforms in for now. On these platforms the
fans will be enabled and then detected - so no impact.

Lenovo AMD based platforms have been offering platform_profiles but they
are not working correctly. This is because the mode we are using on the
Intel platforms (MMC) is not available on the AMD platforms.
This commit adds checking of the functional capabilities returned by the
BIOS to confirm if MMC is supported or not. Profiles will not be
available if the platform is not MMC capable.
I'm investigating and working on an alternative for AMD platforms but
that is still work-in-progress.

Some ThinkPad models, like the X1 Tablet 1st and 2nd Gen, are passively
cooled without any fan. Currently, an entry in /proc/acpi/ibm/fan is
nevertheless created, and misleadingly shows
status: enabled
speed: 65535
level: auto
This patch adds a TPACPI_FAN_NOFAN quirk definition and corresponding
handling to not initialize a fan interface at all.
For the time being, the quirk is only applied for X1 Tablet 2nd Gen
(types 20JB, 20JC; EC N1O...); further models (such as Gen1, types 20GG
and 20GH) can be added easily once tested.
Tested on a 20JCS00C00, BIOS N1OET58W (1.43), EC N1OHT34W.

Allow a privacy screen provider to stash its private data pointer in the
drm_privacy_screen, and update the drm_privacy_screen_register() call to
accept that. Also introduce a *_get_drvdata() so that it can retrieved
back when needed.
This also touches the IBM Thinkpad platform driver, the only user of
privacy screen today, to pass NULL for now to the updated API.

There have been various bugs / forum threads about allowing control of
the LED in the ThinkPad logo on the lid of various models.
This seems to be something which users want to control and there really
is no reason to require setting CONFIG_THINKPAD_ACPI_UNSAFE_LEDS for this.
The lid-logo-dot is LED number 10, so change the name of the 10th led
from unknown_led2 to lid_logo_dot and add it to the TPACPI_SAFE_LEDS mask.

Add the LED_RETAIN_AT_SHUTDOWN flag to the registered led_class_devs so
that the LEDs do not get turned-off when reloading the driver and thus so
that they also stay under default EC control when reloading the driver,
unless explicitly overridden by the user.

Commit c99ca78d67a6 ("platform/x86: thinkpad_acpi: Switch to common use
of attributes") removed the conditional adding of the
hotkey_tablet_mode and hotkey_radio_sw sysfs-attributes, replacing this
with a hotkey_attr_is_visible() callback which hides them when the
feature is not present.
But this commit forgot to add these 2 attributes to the default
hotkey_attributes[] set, so they would now never get added at all.
Add the 2 attributes to the default hotkey_attributes[] set so that
they are available on systems with these features once more.

The hwmon sysfs-attr should show up under the hwmon-classdev, not under
the tpacpi_sensors_pdev. Pass the tpacpi_hwmon_groups attr-groups array
to hwmon_device_register_with_groups() instead of setting
tpacpi_hwmon_pdriver.driver.dev_groups to it to fix this.
This also requires moving the hwmon_device_register_with_groups() call to
after the subdriver init functions have run so that the is_visible()
calls will work properly.

Commit 79f960e29cfc ("platform/x86: thinkpad_acpi: Convert platform driver
to use dev_groups") put the debug_level, interface_version, version and the
THINKPAD_ACPI_DEBUGFACILITIES attributes in a new tpacpi_attr_group and
added those to the tpacpi_groups groups-array which is used to initialize
the driver.dev_groups member.
But before this commit these attributes were registered with
driver_create_file(), so they should be part of the groups-array which is
used to initialize the driver.groups member instead.
And also make the same change for the fan_watchdog hwmon driver attribute.
