Arnold Gozum fcd38f178b platform/x86: intel-vbtn: Support for tablet mode on Dell Inspiron 7352
The Dell Inspiron 7352 is a 2-in-1 model that has chassis-type "Notebook".
Add this model to the dmi_switches_allow_list.

Hans de Goede 46c54cf270 platform/x86: touchscreen_dmi: Add swap-x-y quirk for Goodix touchscreen on Estar Beauty HD tablet
The Estar Beauty HD (MID 7316R) tablet uses a Goodix touchscreen,
with the X and Y coordinates swapped compared to the LCD panel.

Add a touchscreen_dmi entry for this adding a "touchscreen-swapped-x-y"
device-property to the i2c-client instantiated for this device before
the driver binds.

This is the first entry of a Goodix touchscreen to touchscreen_dmi.c,
so far DMI quirks for Goodix touchscreen's have been added directly
to drivers/input/touchscreen/goodix.c. Currently there are 3
DMI tables in goodix.c:
1. rotated_screen[] for devices where the touchscreen is rotated
   180 degrees vs the LCD panel
2. inverted_x_screen[] for devices where the X axis is inverted
3. nine_bytes_report[] for devices which use a non standard touch
   report size

Arguably only 3. really needs to be inside the driver and the other
2 cases are better handled through the generic touchscreen DMI quirk
mechanism from touchscreen_dmi.c, which allows adding device-props to
any i2c-client. Esp. now that goodix.c is using the generic
touchscreen_properties code.

Alternative to the approach from this patch we could add a 4th
dmi_system_id table for devices with swapped-x-y axis to goodix.c,
but that seems undesirable.

Heikki Krogerus 9bba962755 platform/x86: i2c-multi-instantiate: Don't create platform device for INT3515 ACPI nodes
There are several reports about the tps6598x causing
interrupt flood on boards with the INT3515 ACPI node, which
then causes instability. There appears to be several
problems with the interrupt. One problem is that the
I2CSerialBus resources do not always map to the Interrupt
resource with the same index, but that is not the only
problem. We have not been able to come up with a solution
for all the issues, and because of that disabling the device
for now.

The PD controller on these platforms is autonomous, and the
purpose for the driver is primarily to supply status to the
userspace, so this will not affect any functionality.

Geert Uytterhoeven e4a02c7a0e platform/surface: SURFACE_PLATFORMS should depend on ACPI
All Microsoft Surface platform-specific device drivers depend on ACPI,
but the gatekeeper symbol SURFACE_PLATFORMS does not.  Hence when the
user is configuring a kernel without ACPI support, he is still asked
about Microsoft Surface drivers, even though this question is
irrelevant.

Fix this by moving the dependency on ACPI from the individual driver
symbols to SURFACE_PLATFORMS.

Linus Torvalds 605ea5aafe spi: Updates for v5.11
The big change this release has been some excellent work from Lukas
 Wunner which closes a bunch of holes in the cleanup paths for drivers,
 mainly introduced as a result of devm conversions causing bad
 interactions with the support SPI has for allocating the bus and driver
 data together.  Together with some of the other work done it feels like
 we've turned the corner on several long standing pain points with the
 API.
 
  - Many cleanups around probe/remove and error handling from Lukas
    Wunner and Uwe Kleine-König, and further fixes around PM from Zhang
    Qilong.
  - Provide a mask for which bits of the mode can safely be configured by
    drivers and use that to fix an issue with the ADS7846 driver.
  - Documentation of the expected interactions between SPI and GPIO level
    chip select polarity configuration from H. Nikolaus Schaller,
    hopefully we're pretty much at the end of sorting out the
    interactions there.  Thanks to Nikolaus, Sven Van Asbroeck and Linus
    Walleij for this.
  - DMA support for Allwinner sun6i controllers.
  - Support for Canaan K210 Designware implementations and Intel Adler Lake.

platform/chrome: cros_ec_typec: Tolerate unrecognized mux flags
On occasion, the Chrome Embedded Controller (EC) can send a mux
configuration which doesn't map to a particular data mode. For instance,
dedicated Type C chargers, when connected, may cause only
USB_PD_MUX_POLARITY_INVERTED to be set. This is a valid flag combination
and should not lead to a driver abort.

Modify the mux configuration handling to not return an error when an
unrecognized mux flag combination is encountered. Concordantly, make the
ensuing print a debug level print so as to not pollute the kernel logs.

platform/chrome: cros_ec_spi: Don't overwrite spi::mode
There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

Hans de Goede dea5b80a04 platform/x86: intel-hid: Do not create SW_TABLET_MODE input-dev when a KIOX010A ACPI dev is present
Some 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers
to allow the OS to determine the angle between the display and the base
of the device. On Windows these are read by a special HingeAngleService
process which calls an ACPI DSM (Device Specific Method) on the
ACPI KIOX010A device node for the sensor in the display, to let the
firmware know if the 2-in-1 is in tablet- or laptop-mode so that it can
disable the kbd and touchpad to avoid spurious input in tablet-mode.

The linux kxcjk1013 driver calls the DSM for this once at probe time
to ensure that the builtin kbd and touchpad work. On some devices this
causes a "spurious" 0xcd event on the intel-hid ACPI dev. In this case
there is not a functional tablet-mode switch, so we should not register
the tablet-mode switch device.

Daniel Lezcano f34a32fae7 platform/x86/drivers/acerhdf: Check the interval value when it is set
Currently the code checks the interval value when the temperature is
read which is bad for two reasons:

 - checking and setting the interval in the get_temp callback is
   inaccurate and awful, that can be done when changing the value.

 - Changing the thermal zone structure internals is an abuse of the
   exported structure, moreover no lock is taken here.

The goal of this patch is to solve the first item by using the 'set'
function called when changing the interval. The check is done there
and removed from the get_temp function. If the thermal zone was not
initialized yet, the interval is not updated in this case as that will
happen in the init function when registering the thermal zone device.

I don't have any hardware to test the changes.

Hans de Goede a4327979a1 platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on some HP x360 models
Some HP x360 models have an ACPI VGBS method which sets bit 4 instead of
bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT
collection shows only one other model, the Medion E1239T ever setting bit 4
and it always sets this together with bit 6.

So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.

While at it also prefix all VGBS constant defines with "VGBS_".

Note this wrokaround was first added to the kernel as
commit d823346876 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always
reporting 1 on the HP Pavilion 11 x360").
After commit 8169bd3e6e ("platform/x86: intel-vbtn: Switch to an
allow-list for SW_TABLET_MODE reporting") got added to the kernel this
was reverted, because with the new allow-list approach the workaround
was no longer necessary for the model on which the issue was first
reported.

But it turns out that the workaround is still necessary because some
affected models report a chassis-type of 31 which is on the allow-list.

Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake

Recent versions of libinput changed to only process the device state and

The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has

quirk for this. This fixes not being able to set the charging tresholds
on this model; and this alsoe fixes the following errors in dmesg:

thinkpad_acpi: Error probing battery 2

Note that the added quirk is for the "R0K" BIOS versions which are
used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there
is a separate "R0L" BIOS for the i3/i5 based versions. This may also

Hans de Goede f2eae1888c platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e
The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.

The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:

1. Not show the onscreen keyboard when a text-input field is focussed
   with the touchscreen.
2. Disable accelerometer based auto display-rotation.

This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.

Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.

Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

This patch builds on the work done previously for the input device
implementation (which was not needed). Both lap and palm sensor are using
sysfs and they are combined into the proxsensor block.

Note: On some platforms, because of an issue in the HW implementation,
the palm sensor presence may be incorrectly advertised as always
enabled even if a palm sensor is not present. The palm sensor is
intended for WWAN transmission power control and should be available
and correct on all WWAN enabled systems. It is not recommended to use
this interface for other use cases.

Subsequent patches will retrieve and parse the discovery data and fill

Also check the EC_FEATURE_TYPEC_CMD feature flag at probe, and only call
the new TYPEC_STATUS command if the feature flag is supported.

Stephen Boyd 853c1a789f platform/chrome: Don't treat RTC events as wakeup sources
The EC sends an RTC host event when the RTC fires, but we don't need to
treat that as a wakeup event here. The RTC class already properly
handles activating and deactivating a wakeup source in rtc_update_irq()
by calling pm_stay_awake() at the start of processing and pm_relax()
once all expired RTC timers have been processed. This reduces one wakeup
increment but not much else. I noticed this while debugging RTC wakeups
and how they always incremented the wakeup count by two instead of one
because this is duplicated.

Kenneth Chan 25dd390c62 platform/x86: panasonic-laptop: Add sysfs attributes for firmware brightness registers
Panasonic laptops (at least from CF-W4 onwards) have dedicated firmware
registers for saving ac/dc and current brightness. They are a bit confusing
so here's some explanations:

AC_MIN_BRIGHT, AC_MAX_BRIGHT, DC_MIN_BRIGHT, DC_MAX_BRIGHT:
Read-only. Values: 0x01 and 0x15 respectively.

AC_CUR_BRIGHT, DC_CUR_BRIGHT:
Read-Write. 0x00-0xFF. Store user-defined AC/DC brightness. However,
they do not represent current brightness so they should be named AC_BRIGHT
and DC_BRIGHT instead.

CUR_BRIGHT (present since CF-W4):
Read-Write. 0x00-0xFF. It sets the current brightness. It won't update
itself if brightness is changed via other means, e.g. acpi_video0.

Another CUR_BRIGHT (added since CF-W5):
Read-Write. 0x01-0x15. Its value always synchronizes with current
brightness. Not implemented in this version.

Currently the backlight API interacts with AC_CUR_BRIGHT (probably because
it's the only bl register available in earlier models?). This patch adds
sysfs attributes for AC_CUR_BRIGHT, DC_CUR_BRIGHT and CUR_BRIGHT.

It also fixes the error of https://lkml.org/lkml/2020/8/19/1264.

PS: I think the backlight API should interact with CUR_BRIGHT instead of
AC_CUR_BRIGHT. But it involves complications like mapping between 0x01-0x15
or 0x00-0x14 (the backlight API) and 0x00-0xFF (CUR_BRIGHT). I'll leave the
discussion for a later version.

intel_hid_dsm_fn_mask, acquired from function index 0, is "a buffer

it should be compared with corresponding bit.

This buffer is usually longer than a byte. Depending on whether
INTEL_HID_DSM_HEBC_V2_FN exist, it could be either
"Buffer (0x02) { 0xFF, 0x01 }" or "Buffer (0x02) { 0xFF, 0x03 }".
Probably it won't grow larger according to the description. On older
platforms, available functions could be fewer or not supported at all,

Hans de Goede 685489a32c platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e
The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.

The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:

1. Not show the onscreen keyboard when a text-input field is focussed
   with the touchscreen.
2. Disable accelerometer based auto display-rotation.

This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.

Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.

Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

Maximilian Luz 274335f1c5 platform/surface: Add Driver to set up lid GPEs on MS Surface device
Conventionally, wake-up events for a specific device, in our case the
lid device, are managed via the ACPI _PRW field. While this does not
seem strictly necessary based on ACPI spec, the kernel disables GPE
wakeups to avoid non-wakeup interrupts preventing suspend by default and
only enables GPEs associated via the _PRW field with a wake-up capable
device. This behavior has been introduced in commit f941d3e41d ("ACPI:
EC / PM: Disable non-wakeup GPEs for suspend-to-idle") and is described
in more detail in its commit message.

Unfortunately, on MS Surface devices, there is no _PRW field present on
the lid device, thus no GPE is associated with it, and therefore the GPE
responsible for sending the status-change notification to the lid gets
disabled during suspend, making it impossible to wake the device via the
lid.

This patch introduces a pseudo-device and respective driver which, based
on some DMI matching, marks the corresponding GPE of the lid device for
wake and enables it during suspend. The behavior of this driver models
the behavior of the ACPI/PM core for normal wakeup GPEs, properly
declared via the _PRW field.

Alexander Duyck e2729113ce platform/x86: Intel PMT class driver
Intel Platform Monitoring Technology is meant to provide a common way to
access telemetry and system metrics.

Register mappings are not provided by the driver. Instead, a GUID is read
from a header for each endpoint. The GUID identifies the device and is to
be used with an XML, provided by the vendor, to discover the available set
of metrics and their register mapping.  This allows firmware updates to
modify the register space without needing to update the driver every time
with new mappings. Firmware writes a new GUID in this case to specify the
new mapping.  Software tools with access to the associated XML file can
then interpret the changes.

The module manages access to all Intel PMT endpoints on a system,
independent of the device exporting them. It creates an intel_pmt class
to manage the devices. For each telemetry endpoint, sysfs files provide
GUID and size information as well as a pointer to the parent device the
telemetry came from. Software may discover the association between
endpoints and devices by iterating through the list in sysfs, or by looking
for the existence of the class folder under the device of interest.  A
binary sysfs attribute of the same name allows software to then read or map
the telemetry space for direct access.

Hans de Goede 5c54cb6c62 platform/x86: acer-wmi: Add support for SW_TABLET_MODE on Switch devices
Add support for SW_TABLET_MODE on the Acer Switch 10 (SW5-012) and the
acer Switch 10 (S1003) models.

There is no way to detect if this is supported, so this uses DMI based
quirks setting force_caps to ACER_CAP_KBD_DOCK (these devices have no
other acer-wmi based functionality).

The new SW_TABLET_MODE functionality can be tested on devices which
are not in the DMI table by passing acer_wmi.force_caps=0x40 on the
kernel commandline.

Hans de Goede 39aa009bb6 platform/x86: acer-wmi: Add new force_caps module parameter
Add a new force_caps module parameter to allow overriding the drivers
builtin capability detection mechanism.

This can be used to for example:
-Disable rfkill functionality on devices where there is an AA OEM DMI
 record advertising non functional rfkill switches
-Force loading of the driver on devices with a missing AA OEM DMI record

Note that force_caps is -1 when unset, this allows forcing the
capability field to 0, which results in acer-wmi only providing WMI
hotkey handling while disabling all other (led, rfkill, backlight)
functionality.

Samuel Čavoj ea856ec266 platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360
The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).

Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this
WMI device should be used to figure out the SW_TABLET_MODE state, as
opposed to the quirk_asus_use_kbd_dock_devid.

Additionally, the device needs to be queried on resume and restore
because the firmware does not generate an event if the laptop is put to
sleep while in tablet mode, flipped to normal mode, and later awoken.

It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.

The reason for using an allowlist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.

 * TRIO (PCIe root complex)
 * MSS (Memory Sub-system containing the Memory Controller and L3 cache)
 * GIC (Interrupt controller)
 * SMMU (System Memory Management Unit)
The mlx_pmc driver provides access to all of these performance modules
through a hwmon sysfs interface.

This reverts commit 7b11e89896.

Consider the following hardware setting.

|-PNP0C14:00
|  |-- device #1
|-PNP0C14:01
|  |-- device #2

When unloading wmi driver module, device #2 will be first unregistered.
But device_destroy() using MKDEV(0, 0) will locate PNP0C14:00 first
and unregister it. This is incorrect. Should use device_unregister() to
unregister the real parent device.

Maximilian Luz 1e3a2bc89d platform: Add Surface platform directory
It may make sense to split the Microsoft Surface hardware platform
drivers out to a separate subdirectory, since some of it may be shared
between ARM and x86 in the future (regarding devices like the Surface
Pro X).

Further, newer Surface devices will require additional platform drivers
for fundamental support (mostly regarding their embedded controller),
which may also warrant this split from a size perspective.

This commit introduces a new platform/surface subdirectory for the
Surface device family, with subsequent commits moving existing Surface
drivers over from platform/x86.

A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Mark Gross) after they have been reviewed by
Maximilian Luz.

Vadim Pasternak c071afcea6 platform/x86: mlx-platform: Remove PSU EEPROM configuration
Remove PSU EEPROM configuration for systems class equipped with
Mellanox chip Spectrume-2. Till now all the systems from this class
used few types of power units, all equipped with EEPROM device with
address space two bytes. Thus, all these devices have been handled by
EEPROM driver "24c32".
There is a new requirement is to support power unit replacement by "off
the shelf" device, matching electrical required parameters. Such device
could be equipped with different EEPROM type, which could be one byte
address space addressing or even could be not equipped with EEPROM.
In such case "24c32" will not work.

Gayatri Kammela 46461f8709 platform/x86: intel_pmc_core: fix: Replace dev_dbg macro with dev_info()
dev_dbg macro is used to dump the debug registers in resume from an S0ix
failure. However, when CONFIG_DYNAMIC_DEBUG is not set, the user may not be
able to find the debug dump on an S0ix failure which defeats the purpose.
The output of these messages is already controlled by a module parameter,
warn_on_s0ix_failures, making it a 2 step process to enable anyway when
CONFIG_DYNAMIC_DEBUG is set.

Hence, replace dev_dbg with dev_info, allowing the control of the messages
solely through the module parameter which is N by default.

Fixes commit 913f984a83 ("platform/x86: intel_pmc_core: Add an
additional parameter to pmc_core_lpm_display()")

  These regressions were caused by the asus-nb-wmi and the intel-vbtn

  to report it on more models.

Hans de Goede 1797d588af platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
Commit b0dbd97de1 ("platform/x86: asus-wmi: Add support for
SW_TABLET_MODE") added support for reporting SW_TABLET_MODE using the
Asus 0x00120063 WMI-device-id to see if various transformer models were
docked into their keyboard-dock (SW_TABLET_MODE=0) or if they were
being used as a tablet.

The new SW_TABLET_MODE support (naively?) assumed that non Transformer
devices would either not support the 0x00120063 WMI-device-id at all,
or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying
the device-id.

Unfortunately this is not true and we have received many bug reports about
this change causing the asus-wmi driver to always report SW_TABLET_MODE=1
on non Transformer devices. This causes libinput to think that these are
360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput
suppress keyboard and touchpad events from the builtin keyboard and
touchpad. So effectively this causes the keyboard and touchpad to not work
on many non Transformer Asus models.

This commit fixes this by using the existing DMI based quirk mechanism in
asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting
SW_TABLET_MODE on Transformer models and ignoring it on all other models.

Hans de Goede 8169bd3e6e platform/x86: intel-vbtn: Switch to an allow-list for SW_TABLET_MODE reporting
2 recent commits:
cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE
on the 9 / "Laptop" chasis-type")
1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on
"Detachable" and "Portable" chassis-types")

Enabled reporting of SW_TABLET_MODE on more devices since the vbtn ACPI
interface is used by the firmware on some of those devices to report this.

Testing has shown that unconditionally enabling SW_TABLET_MODE reporting
on all devices with a chassis type of 8 ("Portable") or 10 ("Notebook")
which support the VGBS method is a very bad idea.

Many of these devices are normal laptops (non 2-in-1) models with a VGBS
which always returns 0, which we translate to SW_TABLET_MODE=1. This in
turn causes userspace (libinput) to suppress events from the builtin
keyboard and touchpad, making the laptop essentially unusable.

Since the problem of wrongly reporting SW_TABLET_MODE=1 in combination
with libinput, leads to a non-usable system. Where as OTOH many people will
not even notice when SW_TABLET_MODE is not being reported, this commit
changes intel_vbtn_has_switches() to use a DMI based allow-list.

The new DMI based allow-list matches on the 31 ("Convertible") and
32 ("Detachable") chassis-types, as these clearly are 2-in-1s and
so far if they support the intel-vbtn ACPI interface they all have
properly working SW_TABLET_MODE reporting.

Besides these 2 generic matches, it also contains model specific matches
for 2-in-1 models which use a different chassis-type and which are known
to have properly working SW_TABLET_MODE reporting.

This has been tested on the following 2-in-1 devices:

Dell Venue 11 Pro 7130 vPro
HP Pavilion X2 10-p002nd
HP Stream x360 Convertible PC 11
Medion E1239T

A struct device is a dynamic structure, with reference counting.
"Tricking" the kernel to make a dynamic structure static, by working
around the driver core release detection logic, is not nice.

Because of this, this code has been used as an example for others on
"how to do things", which is just about the worst thing possible to have
happen.

Fix this all up by making the platform device dynamic and providing a
real release function.

Hans de Goede d823346876 platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP Pavilion 11 x360
Commit cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").

It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.

The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.

So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.

While at it also prefix all VGBS constant defines with "VGBS_".

Hans de Goede 8a333dab28 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 b5f7311d3a ("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. I have another patch fixing the LED
issue in a different manner.

Note this is the second time the we revert the adding of the
asus_nb_wmi_blacklist. It was reverted before in commit:

aab9e7896e ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus
T100TA and T200TA")"

But some how (accidentally re-applying of the patch?) it got re-added
again in commit 3bd12da7f5 ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA"), so now we need to revert it again.

Since all the other call-sites of cros_ec_cmd_xfer() have been converted
to use cros_ec_cmd_xfer_status() instead, update the remaining
call-sites to prepare for the merge of cros_ec_cmd_xfer() into
cros_ec_cmd_xfer_status().

As part of this update, change the error handling inside
cros_ec_get_sensor_count() such that the legacy LPC interface is tried
on all error values, not just when msg->result != EC_RESULT_SUCCESS.

Note that there is a slight change in API in cros_ec_get_sensor_count():
it will return a negative number of sensors when there are no sensors
on arm platform when MOTIONSENSE_CMD_DUMP is not supported (typical for
sensorless chromebook) instead of 0. However, this is not a problem when
probing the EC as we ignore errors only looking for cros_ec_get_sensor_count()
returning a positive number of sensors.

Hans de Goede e2c8c4ec48 platform/x86: thinkpad_acpi: Map Clipping tool hotkey to KEY_SELECTIVE_SCREENSHOT
Commit 696c6523ec ("platform/x86: thinkpad_acpi: add mapping for new
hotkeys") added support for a bunch of new hotkeys, but the
clipping/snipping tool hotkey got ignored because there was no good
key-code to map it to.

Recently a new KEY_SELECTIVE_SCREENSHOT keycode was added by commit
3b059da983 ("Input: allocate keycode for "Selective Screenshot" key")
quoting from the commit message:

"New Chrome OS keyboards have a "snip" key that is basically a selective
screenshot (allows a user to select an area of screen to be copied).
Allocate a keycode for it."

Support for this "snip" key seems like it is also a good match for the
clipping/snipping tool hotkey, so map this hotkey to the new
KEY_SELECTIVE_SCREENSHOT key-code.

Fn + right Shift key-combo is pressed.

This commit adds support for these 4 new hkey events.

flow for configuring a device connected to a typeC port is as below:

1. Source/sink detection
2. Orientation
3. Data role
4. VCONN
5. VBUS (USB Type-C currents)
6. The connector is now configured. We can start the PD communication
   that should lead into configuration of the mux if we enter a mode.

But in existing code data role was set after the connector and mux are
already configured. So fix this by following the spec to set the data
role before the connector and mux are configured.

Guenter Roeck 0d080459e8 platform/chrome: cros_ec_proto: Convert EC error codes to Linux error codes
The EC reports a variety of error codes. Most of those, with the exception
of EC_RES_INVALID_VERSION, are converted to -EPROTO. As result, the actual
EC error code gets lost. Introduce cros_ec_map_error() to map EC error
codes to Linux error codes, and use it in cros_ec_cmd_xfer_status() to
report more meaningful errors to the caller. With this change, callers of
cros_ec_cmd_xfer_status() can implement a more distinguished action without
having to rely on the EC error code. At the same time, debugging is improved
in situations where the Linux error code is reported to userspace and/or in
the kernel log.

Linus Torvalds c0c419c045 Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

Linus Torvalds 6d2b84a4e5 This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code.
 
 The three APIs for non-scheduler code to set SCHED_FIFO are:
 
  - sched_set_fifo()
  - sched_set_fifo_low()
  - sched_set_normal()
 
 These are two FIFO priority levels: default (high), and a 'low' priority level,
 plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
 
 Since the changes affect a lot of non-scheduler code, we kept this in a separate
 tree.
 
 When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
 which can be resolved via:
 
 	sched_set_fifo(ctlr->kworker_task);

Michael S. Tsirkin 03bea764bf mlxbf-tmfifo: sparse tags for config access
mlxbf-tmfifo accesses config space using native types -
which works for it since the legacy virtio native types.

This will break if it ever needs to support modern virtio,
so with new tags previously introduced for virtio net config,
sparse now warns for this in drivers.

Since this is a legacy only device, fix it up using
virtio_legacy_is_little_endian for now.

No functional changes.

Brian Norris fc8cacf3fc platform/chrome: cros_ec_proto: check for missing EC_CMD_HOST_EVENT_GET_WAKE_MASK
As with cros_ec_cmd_xfer_status(), etc., it's not enough to simply check
for the return status of send_command() -- that only covers transport or
other similarly-fatal errors. One must also check the ->result field, to
see whether the command really succeeded. If not, we can't use the data
it returns.

The caller of cros_ec_get_host_event_wake_mask() ignores this, and so
for example, on EC's where the command is not implemented, we're using
junk (or in practice, all zeros) for our wake-mask. We should be using a
non-zero default (currently, it's supposed to be all-1's).

Fix this by checking the ->result field and returning -EPROTO for
errors.

I might label this as fixing commit 29d99b966d ("cros_ec: Don't signal
wake event for non-wake host events"), except that this fix alone
actually may make things worse, as it now allows for a lot more spurious
wakeups. The patch "platform/chrome: cros_ec_proto: ignore battery/AC
wakeups on old ECs" helps to mitigate this.

Brian Norris c214e564ac platform/chrome: cros_ec_proto: ignore unnecessary wakeups on old ECs
ECs that don't implement EC_CMD_HOST_EVENT_GET_WAKE_MASK should still
have some reasonable default mask -- otherwise, they'll treat a variety
of EC signals as spurious wakeups. Battery and AC events can be
especially common, for devices that have been sitting at full charge
plugged into AC for a long time, as they may cycle their charging off
and on, or their battery may start reporting failures as it ages.

Treating these as wakeups does not serve a useful purpose, and is
instead often counterproductive. And indeed, later ECs (that implement
the mask) don't include these events in their wake-mask.

Note that this patch doesn't do anything without the subsequent patch
("platform/chrome: cros_ec_proto: check for missing
EC_CMD_HOST_EVENT_GET_WAKE_MASK"), because
cros_ec_get_host_event_wake_mask() currently does not return an error if
EC_CMD_HOST_EVENT_GET_WAKE_MASK is not implemented.

Some additional notes:
While the EC typically knows not to wake the CPU for these unimportant
events once the CPU reaches a sleep state, it doesn't really have a way
to know that the CPU is "almost" asleep, unless it has support for
EC_CMD_HOST_SLEEP_EVENT. Alas, these older ECs do not support that
command either, so this solution is not 100% complete.

Gwendal Grignou 7f4784f188 platform/chrome: cros_ec_sensorhub: Simplify legacy timestamp spreading
On some machines (nami), interrupt latency cause samples to appear
to be from the future and are pegged to the current time.
We would see samples with this pattern:

[t, t + ~5ms, t + ~10ms, t + ~10ms + 100us, t + ~10ms + 200us],
                             (current now)      (current now)
(t is the last timestamp time)

Last 2 samples would be barely spread, causing applications to
complain.

We now spread the entire sequence. This is not great: in the example
the sensor was supposed to send samples every 5ms, it now appears to
send one every 2.5ms, but it is slightly closer to reality:

sampling time in the example above

Kees Cook 3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

Florian Eckert f560cd5021 platform/x86: pcengines-apuv2: revert wiring up simswitch GPIO as LED
This reverts commit 5037d4ddda.

Explanation why this does not work:
This change connects the simswap to the LED subsystem of the kernel.
From my point of view, it's nonsense. If we do it this way, then this
can be switched relatively easily via the LED subsystem (trigger:
none/default-on) and that is dangerous! If this is used, it would be
unfavorable, since there is also another trigger (trigger:
heartbeat/netdev).

Therefore, this simswap GPIO should remain in the GPIO
subsystem and be switched via it and not be connected to the LED
subsystem. To avoid the problems mentioned above. The LED subsystem is
not made for this and it is not a good compromise, but rather dangerous.
