After more discussions with the [libinput project][1], it has been
determined that the uclogic driver provides better support for this
tablet. Fortunately, the Trust Panora is physically and logically
identical with the UGEE G5, despite having a different USB vendor and
product ID.

The DualSense features 5 player LEDs below its touchpad, which are
meant as player id indications. The LEDs are configured with a
player ID determined by an ID allocator, which assign player ids
to ps_device instances.
This patch is a combination of the following original patches
minus use of LED framework APIs:
- HID: playstation: add DualSense player LEDs support.
- HID: playstation: DualSense set LEDs to default player id.

The DualSense controller has a built-in microphone exposed as an
audio device over USB (or HID using Bluetooth). A dedicated
button on the controller handles mute, but software has to configure
the device to mute the audio stream.
This patch captures the mute button and schedules an output report
to mute/unmute the audio stream as well as toggle the mute LED.

The DualSense features a haptics system based on voicecoil motors,

This patch adds support for the DualSense when operating in Bluetooth mode.
The device has the same behavior as the DualShock 4 in that by default it
sends a limited input report (0x1), but after requesting calibration data,
it switches to an extended input report (report 49), which adds data for
touchpad, motion sensors, battery and more.

The current implementation would set the latency to normal on device initialization,
but we didn't set the device to high latency on suspend.

This new feature present in new devices replaces the old Battery Level Status
(0x1000) feature. It keeps essentially the same information for levels
(reporting critical, low, good and full) but makes these levels optional, the
device exports a capability setting which describes which levels it supports.
In addition to this, there is an optional state_of_charge paramenter that
exports the battery percentage.
This patch adds support for this new feature. There were some implementation
choices, as described below and in the code.
If the device supports the state_of_charge parameter, we will just export the
battery percentage and not the levels, which the device might still support.
Since this feature can co-exist with the Battery Voltage (0x1001) feature and
we currently only support one battery feature, I changed the battery feature
discovery to try to use 0x1000 and 0x1004 first and only then 0x1001, the
battery voltage feature.
In the future we could uncouple this and make the battery feature co-exists
with 0x1000 and 0x1004, allowing the device to export voltage information in
addition to the battery percentage or level.
I tested this patch with a MX Anywhere 3, which supports the new feature. Since
I don't have any device that doesn't support the state_of_charge parameter of
this feature, I forced the MX Anywhere 3 to use the level information, instead
of battery percentage, to test that part of the implementation.
I also tested with a MX Master 3, which supports the Battery Level Status
(0x1000) feature, and a G703 Hero, which supports the Battery Voltage (0x1001)
feature, to make sure nothing broke there.

When OOB is disabled, FW will be power gated when system is in S3/S4/S5
which is the same behavior with legacy ISH FW.
When OOB is enabled, FW will always power on which is totally different
comparing to legacy ISH FW.
So NO_D3 flag is not enough to check FW's status after resume.
Here we can use IPC FW status register to check host link status.
If it is false, it means FW get reset after power gated, need go through
the whole initialization flow; If it is true, it means FW is alive, just
set host ready bit to let fw know host is up.

The EHL (Elkhart Lake) based platforms provide a OOB (Out of band)
service, which allows wakup device when the system is in S5 (Soft-Off
state). This OOB service can be enabled/disabled from BIOS settings. When
enabled, the ISH device gets PME wake capability. To enable PME wakeup,
driver also needs to enable ACPI GPE bit.
Once wakeup, BIOS will clear the wakeup bit to identify wakeup is
successful. So driver need to re-enable it in resume function to
keep the next wakeup capability.
Since this feature is only present on EHL, we use EHL PCI device id to
enable this feature.

Goodix i2c-hid touchscreens are mostly i2c-hid compliant but have some
special power sequencing requirements, including the need to drive a
reset line during the sequencing.
Let's use the new rejiggering of i2c-hid to support this with a thin
wrapper driver to support the first Goodix i2c-hid touchscreen:

This patch rejiggers the i2c-hid code so that the OF (Open Firmware
aka Device Tree) and ACPI support is separated out a bit. The OF and
ACPI drivers are now separate modules that wrap the core module.
Essentially, what we're doing here:
* Make "power up" and "power down" a function that can be (optionally)
implemented by a given user of the i2c-hid core.
* The OF and ACPI modules are drivers on their own, so they implement
probe / remove / suspend / resume / shutdown. The core code
provides implementations that OF and ACPI can call into.
We'll organize this so that we now have 3 modules: the old i2c-hid
module becomes the "core" module and two new modules will depend on
it, handling probing the specific device.
As part of this work, we'll remove the i2c-hid "platform data"
concept since it's not needed.

This forces reading the base folded state anytime the device is
probed, to make sure it's in sync.
This is useful after a reboot, if the device re-enumerates for
any reason (e.g. ESD shock), or if the driver is unbound/rebound
(debugging/testing).
Without this, the tablet switch state is only synchronized after a
key is pressed (since the device would then send a report that
includes the switch state), leading to strange UX (e.g. UI
mode changes when a key is pressed after reboot).
This is not a problem on detachable base attach, as the device,
by itself, sends a report after it is booted up.

with 0x11 as the report ID and 0x1 as the value when the key is pressed
down.
This patch maps the event as KEY_RFKILL.

- improved handling of generic HID keyboard (no more splitting system
and consumer controls away), in order to make it easier for userspace
to figure out the details of the device easier. From Dmitry Torokhov.

A typical USB keyboard usually splits its keys into several reports:
- one for the basic alphanumeric keys, modifier keys, F<n> keys, six pack
keys and keypad. This report's application is normally listed as
GenericDesktop.Keyboard
- a GenericDesktop.SystemControl report for the system control keys, such
as power and sleep
- Consumer.ConsumerControl report for multimedia (forward, rewind,
play/pause, mute, etc) and other extended keys.
- additional output, vendor specific, and feature reports
Splitting each report into a separate input device is wasteful and even
hurts userspace as it makes it harder to determine the true capabilities
(set of available keys) of a keyboard, so let's adjust application
matching to merge system control and consumer control reports with
keyboard report, if one has already been processed.

The HID subsystem allows an "HID report field" to have a different
number of "values" and "usages" when it is allocated. When a field
struct is created, the size of the usage array is guaranteed to be at
least as large as the values array, but it may be larger. This leads to
a potential out-of-bounds write in
__hidinput_change_resolution_multipliers() and an out-of-bounds read in
hidinput_count_leds().
To fix this, let's make sure that both the usage and value arrays are
the same size.

Prevent invalid (0, 0) inputs to hid-core's snto32() function.
Maybe it is just the dummy device here that is causing this, but
there are hundreds of calls to snto32(0, 0). Having n (bits count)
of 0 is causing the current UBSAN trap with a shift value of
0xffffffff (-1, or n - 1 in this function).
Either of the value to shift being 0 or the bits count being 0 can be
handled by just returning 0 to the caller, avoiding the following
complex shift + OR operations:
return value & (1 << (n - 1)) ? value | (~0U << n) : value;

The `wacom_feature_mapping` function is careful to only set the the
touch_max value a single time, but this care does not extend to the
`wacom_wac_finger_event` function. In particular, if a device sends
multiple HID_DG_CONTACTMAX items in a single feature report, the
driver will end up retaining the value of last item.
The HID descriptor for the Cintiq Companion 2 does exactly this. It
incorrectly sets a "Report Count" of 2, which will cause the driver
to process two HID_DG_CONTACTCOUNT items. The first item has the actual
count, while the second item should have been declared as a constant
zero. The constant zero is the value the driver ends up using, however,
since it is the last HID_DG_CONTACTCOUNT in the report.
Report ID (16),
Usage (Contact Count Maximum), ; Contact count maximum (55h, static value)
Report Count (2),
Logical Maximum (10),
Feature (Variable),
To address this, we add a check that the touch_max is not already set
within the `wacom_wac_finger_event` function that processes the
HID_DG_TOUCHMAX item. We emit a warning if the value is set and ignore
the updated value.
This could potentially cause problems if there is a tablet which has
a similar issue but requires the last item to be used. This is unlikely,
however, since it would have to have a different non-zero value for
HID_DG_CONTACTMAX earlier in the same report, which makes no sense
except in the case of a firmware bug. Note that cases where the
HID_DG_CONTACTMAX items are in different reports is already handled
(and similarly ignored) by `wacom_feature_mapping` as mentioned above.

The Acer Aspire Switch 10E (SW3-016)'s keyboard-dock uses the same USB-ids
as the Acer One S1003 keyboard-dock. Yet they are not entirely the same:
1. The S1003 keyboard-dock has the same report descriptors as the
S1002 keyboard-dock (which has different USB-ids)
2. The Acer Aspire Switch 10E's keyboard-dock has different
report descriptors from the S1002/S1003 keyboard docks and it
sends 0x00880078 / 0x00880079 usage events when the touchpad is
toggled on/off (which is handled internally).
This means that all Acer kbd-docks handled by the hid-ite.c drivers
report their touchpad being toggled on/off through these custom
usage-codes with the exception of the S1003 dock, which likely is
a bug of that dock.
Add a QUIRK_TOUCHPAD_ON_OFF_REPORT quirk for the Aspire Switch 10E / S1003
usb-id so that the touchpad toggling will get reported to userspace on
the Aspire Switch 10E.
Since the Aspire Switch 10E's kbd-dock has different report-descriptors,
this also requires adding support for fixing those to ite_report_fixup().
Setting the quirk will also cause ite_report_fixup() to hit the
S1002/S1003 descriptors path on the S1003. Since the S1003 kbd-dock
never generates any input-reports for the fixed up part of the
descriptors this does not matter; and if there are versions out there
which do actually send input-reports for the touchpad-toggle then the
fixup should actually help to make things work.
This was tested on both an Acer Aspire Switch 10E and on an Acer One S1003.

This new connection type is the new iteration of the Lightspeed
connection and will probably be used in some of the newer gaming
devices. It is currently use in the G Pro X Superlight.
This patch should be backported to older versions, as currently the
driver will panic when seing the unsupported connection. This isn't
an issue when using the receiver that came with the device, as Logitech
has been using different PIDs when they change the connection type, but
is an issue when using a generic receiver (well, generic Lightspeed
receiver), which is the case of the one in the Powerplay mat. Currently,
the only generic Ligthspeed receiver we support, and the only one that
exists AFAIK, is ther Powerplay.
As it stands, the driver will panic when seeing a G Pro X Superlight
connected to the Powerplay receiver and won't send any input events to
userspace! The kernel will warn about this so the issue should be easy
to identify, but it is still very worrying how hard it will fail :(

In e400071a805d6229223a98899e9da8c6233704a1 I added support for the
receiver that comes with the G602 device, but unfortunately I screwed up
during testing and it seems the keyboard events were actually not being
sent to userspace.
This resulted in keyboard events being broken in userspace, please
backport the fix.
The receiver uses the normal 0x01 Logitech keyboard report descriptor,
as expected, so it is just a matter of flagging it as supported.

Winpad A15
The ITE8568 EC on the Voyo Winpad A15 presents itself as an I2C-HID
attached keyboard and mouse (which seems to never send any events).
This needs the I2C_HID_QUIRK_NO_IRQ_AFTER_RESET quirk, otherwise we get
the following errors:
[ 3688.770850] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3694.915865] i2c_hid i2c-ITE8568:00: failed to reset device.

[ 3708.236518] i2c_hid: probe of i2c-ITE8568:00 failed with error -61
Which leads to a significant boot delay.
