Mark Pearson bce6243f76 platform/x86: thinkpad_acpi: do not use PSC mode on Intel platforms
PSC platform profile mode is only supported on Linux for AMD platforms.

Some older Intel platforms (e.g T490) are advertising it's capability
as Windows uses it - but on Linux we should only be using MMC profile
for Intel systems.

Add a check to prevent it being enabled incorrectly.

Mark Pearson 42504af775 platform/x86: thinkpad-acpi: profile capabilities as integer
Currently the active mode (PSC/MMC) is stored in an enum and queried
throughout the driver.

Other driver changes will enumerate additional submodes that are relevant
to be tracked, so instead track PSC/MMC in a single integer variable.

Jean Delvare d2f33f0c3a platform/x86: thinkpad_acpi: Fix a memory leak of EFCH MMIO resource
Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak.

Mark Pearson aa2fef6f40 platform/x86: thinkpad_acpi: Correct dual fan probe
There was an issue with the dual fan probe whereby the probe was
failing as it assuming that second_fan support was not available.

Corrected the logic so the probe works correctly. Cleaned up so
quirks only used if 2nd fan not detected.

Tested on X1 Carbon 10 (2 fans), X1 Carbon 9 (2 fans) and T490 (1 fan)

Mario Limonciello 455cd867b8 platform/x86: thinkpad_acpi: Add a s2idle resume quirk for a number of laptops
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.

Mark Pearson bf779aaf56 platform/x86: thinkpad_acpi: Add dual fan probe
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.

Mark Pearson 836f35f791 platform/x86: thinkpad_acpi: Fix incorrect use of platform profile on AMD platforms
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.

Alexander Kobel b288420e77 platform/x86: thinkpad_acpi: Add quirk for ThinkPads without a fan
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.

Rajat Jain 30598d925d drm/privacy_screen: Add drvdata in drm_privacy_screen
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.

Merge v5.16-rc5 into drm-next

Thomas Zimmermann requested a fixes backmerge, specifically also for
96c5f82ef0 ("drm/vc4: fix error code in vc4_create_object()")

Just a bunch of adjacent changes conflicts, even the big pile of them
in vc4.

Hans de Goede e1dbdd2f4a platform/x86: thinkpad_acpi: Add lid_logo_dot to the list of safe LEDs
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.

Hans de Goede b68f8a13e3 platform/x86: thinkpad_acpi: Restore missing hotkey_tablet_mode and hotkey_radio_sw sysfs-attr
Commit c99ca78d67 ("platform/x86: thinkpad_acpi: Switch to common use

hotkey_tablet_mode and hotkey_radio_sw sysfs-attributes, replacing this
with a hotkey_attr_is_visible() callback which hides them when the

But this commit forgot to add these 2 attributes to the default

Hans de Goede 526ac103db platform/x86: thinkpad_acpi: Fix the hwmon sysfs-attr showing up in the wrong place
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

Commit 79f960e29c ("platform/x86: thinkpad_acpi: Convert platform driver

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.

Hans de Goede 2f5ad08f3e platform/x86: thinkpad_acpi: Register tpacpi_pdriver after subdriver init
Commit 79f960e29c ("platform/x86: thinkpad_acpi: Convert platform driver
to use dev_groups") introduces the use of driver.dev_groups +
attribute_group.is_visible callbacks replacing the conditional calling of
driver_create_file() for optional attributes.

The is_visible callbacks rely on various tp_features.has_foo flags,
which get set by the subdriver init functions.

But before this fix, thinkpad_acpi_module_init() would call the
subdriver init functions after registering the platform_device and
the tpacpi_pdriver. Which would cause the is_visible callbacks to
get called before the subdriver init functions, which in turn would
cause optional attributes to not get registered at all, even when
the feature is actually present.

Fix this by moving the platform_driver_register(&tpacpi_pdriver) to after
the subdriver init calls; and do the same for the tpacpi_hmon_pdriver.

Hans de Goede 0b0d2fba4f platform/x86: thinkpad_acpi: Cleanup dytc_profile_available
Remove the dytc_profile_available check from dytc_profile_set(),
that function only gets called if the platform_profile_handler was
registered, so the check is not necessary.

Make tpacpi_dytc_profile_init() return -ENODEV when it does not register
the platform_profile() handler this will cause
dytc_profile_driver_data.flags.init to not get set, which in turn will
cause the dytc_profile_exit() call to get skipped.

Together this avoids the need to have the dytc_profile_available
variable at all, since the information is now duplicated in the
dytc_profile_driver_data.flags.init flag.

Note this leaves a weirdly indented code-block behind, this is
deliberately done to make what actually changes in this commit clear.
This will be fixed-up in the next commit.

Hans de Goede 5a47ac0041 platform/x86: thinkpad_acpi: Simplify dytc_version handling
The only reason the proxysensor code needs dytc_version handling is for
proxsensor_attr_is_visible() and that will only ever get called after
all the subdrv init() callbacks have run.

tpacpi_dytc_profile_init() already calls DYTC_CMD_QUERY and is the
primary consumer of dytc_version, so simply let tpacpi_dytc_profile_init()
set dytc_version and remove the now no longer necessary dytc_get_version()
helper and its calls.

Hans de Goede c15f86856b platform/x86: thinkpad_acpi: Accept ibm_init_struct.init() returning -ENODEV
Commit 79f960e29c ("platform/x86: thinkpad_acpi: Convert platform driver
to use dev_groups") accidentally modified tpacpi_kbdlang_init() causing it
to return -ENODEV instead of 0 on machines without kbdlang support
(which are most of them).

ibm_init() sees this -ENODEV as an error causing the entire module to not
load, not good.

Note that technically tpacpi_kbdlang_init() was already buggy before, it
should have returned 1 instead of 0 if the feature is not present.

Rather then fixing tpacpi_kbdlang_init() though, IMHO it is bettter to
just make ibm_init() treat -ENODEV as 1 to fix the issue; and then in
a followup commit also change all the existing "return 1"s from
ibm_init_struct.init() callbacks to "return -ENODEV" as -ENODEV clearly
states what it going on where as a magic return of "1" requires a deep
dive into the code to figure out what is going on.

This will also allow removing some extra ifs to translate -ENODEV to
return 1 in a couple of init() callbacks.

Slark Xiao 39f5329218 platform/x86: thinkpad_acpi: Fix WWAN device disabled issue after S3 deep
When WWAN device wake from S3 deep, under thinkpad platform,
WWAN would be disabled. This disable status could be checked
by command 'nmcli r wwan' or 'rfkill list'.

Issue analysis as below:
  When host resume from S3 deep, thinkpad_acpi driver would
call hotkey_resume() function. Finnaly, it will use
wan_get_status to check the current status of WWAN device.
During this resume progress, wan_get_status would always
return off even WWAN boot up completely.
  In patch V2, Hans said 'sw_state should be unchanged
after a suspend/resume. It's better to drop the
tpacpi_rfk_update_swstate call all together from the
resume path'.
  And it's confimed by Lenovo that GWAN is no longer
 available from WHL generation because the design does not
 match with current pin control.

Len Baker 79f960e29c platform/x86: thinkpad_acpi: Convert platform driver to use dev_groups
Platform drivers have the option of having the platform core create and
remove any needed sysfs attribute files. So take advantage of that and
refactor the attributes management to avoid to register them "by hand".

Also, due to some attributes are optionals, refactor the code and move
the logic inside the "is_visible" callbacks of the attribute_group
structures.

Nathan Chancellor fd96e35ea7 platform/x86: thinkpad_acpi: Fix bitwise vs. logical warning
A new warning in clang points out a use of bitwise OR with boolean
expressions in this driver:

drivers/platform/x86/thinkpad_acpi.c:9061:11: error: use of bitwise '|' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
        else if ((strlencmp(cmd, "level disengaged") == 0) |
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                                           ||
drivers/platform/x86/thinkpad_acpi.c:9061:11: note: cast one or both operands to int to silence this warning
1 error generated.

This should clearly be a logical OR so change it to fix the warning.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
