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.

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

Add support to thinkpad_acpi for returning the status of the palm
sensor.
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.

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.

According to the ACPI spec 9.1.1 _DSM (Device Specific Method),
intel_hid_dsm_fn_mask, acquired from function index 0, is "a buffer
containing one bit for each function index". When validitaing fn_index,
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,

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:

Merge tag 'ib-mfd-x86-v5.11' into review-hans
Immutable branch between MFD and x86 due for the v5.11 merge window
Add support for the Intel Platform Monitoring Technology crashlog
interface. This interface provides a few sysfs values to allow for
controlling the crashlog telemetry interface as well as a character
driver to allow for mapping the crashlog memory region so that it can be
accessed after a crashlog has been recorded.
This driver is meant to only support the server version of the crashlog
which is identified as crash_type 1 with a version of zero. Currently no
other types are supported.

PMT Telemetry is a capability of the Intel Platform Monitoring Technology.
The Telemetry capability provides access to device telemetry metrics that
provide hardware performance data to users from read-only register spaces.
With this driver present the intel_pmt directory can be populated with
telem<x> devices. These devices will contain the standard intel_pmt sysfs
data and a "telem" binary sysfs attribute which can be used to access the
telemetry data.
Also create a PCI device id list for early telemetry hardware that require
workarounds for known issues.
