c980512b45 HID: asus: filter G713/G733 key event to prevent shutdown
The G713 and G733 both emit an unexpected keycode on some key
presses such as Fn+Pause. The device in this case is emitting
two events on key down, and 3 on key up, the third key up event
is report ID 0x02 and is unfiltered, causing incorrect event.

This patch filters out the single problematic event.

7383354ad5 HID: logitech-dj/hidpp: Add info/warn/err messages about 27 MHz keyboard encryption
By default 27 MHz Logitech keyboards send the keypresses to the receiver
in plain text. Logitech's Windows "Keyboard and Mouse settings" tool allows
configuring encryption for the keyboard wireless link.

Now there also is a Linux tool for setting this up:
https://gitlab.freedesktop.org/jwrdegoede/logitech-27mhz-keyboard-encryption-setup

Once a keyboard is paired in encrypted mode, it will no longer work with
any receiver other then the receiver it was paired with.
If a user accidentally tries to pair another keyboard with the receiver
with which a keyboard has been paired in encrypted mode, then the receiver
looses the encryption key and the originally paired keyboard will no longer
work with either that receiver, or another receiver until the keyboard's
encryption key is rewritten by another encrypted mode pairing using the
tool. Or until it is reset by following a special reset procedure.

This commit adds 3 new log messages related to 27 MHz keyboard link
encryption to the Logitech dj / hidpp drivers:

1. An info level message when keyboard encryption is being used
2. A warning message when keyboard encryption is not used
3. An error message when the encryption key has been lost and the
   keyboard will not work because of this

Messages 2. and 3. contain a link to the userspace tool to setup the
encryption. The linked page also contains instructions to clear the key
(without needing the tool) to help a user recover from the keyboard not
working in case 3.

ed80bdc457 HID: quirks: Add HID_QUIRK_NO_INIT_REPORTS quirk for Dell K15A keyboard-dock
Just like the K12A the Dell K15A keyboard-dock has problems with
get_feature requests. This sometimes leads to several
"failed to fetch feature 8" messages getting logged, after which the
touchpad may or may not work.

Just like the K15A these errors are triggered by undocking and docking
the tablet.

There also seem to be other problems when undocking and then docking again
in quick succession. It seems that in this case the keyboard-controller
still retains some power from capacitors and does not go through a
power-on-reset leaving it in a confuses state, symptoms of this are:

1. The USB-ids changing to 048d:8910
2. Failure to read the HID descriptors on the second (mouse) USB intf.
3. The touchpad freezing after a while

These problems can all be cleared by undocking the keyboard and waiting
a full minute before redocking it. Unfortunately there is nothing we can
do about this in the kernel.

The Saitek X65 joystick has a pair of axes that were used as mouse
pointer controls by the Windows driver. The corresponding usage page is
the Game Controls page, which is not recognized by the generic HID
driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes
the second axis get mapped to ABS_MISC+1, and therefore made available
separately.

6a01268687 HID: semitek: new driver for GK6X series keyboards
A number of USB keyboards, using the Semitek firmware, are capable of
handling arbitrary N-key rollover, but due to a buggy report
descriptor, keys beyond the sixth cannot be detected by the generic
HID driver.

There are numerous hardware variants sold by several vendors, mostly
using generic names like "GK61" for the 61-key version.  These
keyboards are sometimes known collectively as the "GK6X" series.

The keyboard has three USB interfaces.  Interface 0 uses the standard
HID boot protocol, limited to eight modifier keys and six normal keys;
interface 2 uses a custom report format that permits any number of
keys.  If more than six keys are pressed simultaneously, the first six
are reported via interface 0 while subsequent keys are reported via
interface 2.

(Interface 1 uses a custom protocol for reprogramming the keyboard;
this can be controlled through userspace tools and is not of concern
for the present driver.)

The report descriptor for interface 2, however, is incorrect (for
report ID 0x04, the input field is marked as "array" rather than
"variable".)  The descriptor appears to be correct in other respects,
so we simply replace the incorrect byte before parsing the descriptor.

This is the capacity in percentage, relative to design capacity.
Specifically, it is present in Apple Magic Mouse 2.

In contrast, usage 00850064 is also the capacity in percentage, but is
relative to full capacity. It is not mapped here because I don't have
such device.

c0dc558281 HID: magicmouse: fix reconnection of Magic Mouse 2
It is observed that the Magic Mouse 2 would not enter multi-touch mode
unless the mouse is connected before loading the module. It seems to be
a quirk specific to Magic Mouse 2

Retrying after 500ms fixes the problem for me. The delay can't be
reduced much further --- 300ms didn't work for me. Retrying immediately
after receiving an event didn't work either.

3dcc5f7b45 HID: magicmouse: fix 3 button emulation of Mouse 2
It is observed that, with 3 button emulation, when middle button is
clicked, either the left button or right button is clicked as well. It
is caused by hidinput "correctly" acting on the event, oblivious to the
3 button emulation.

As raw_event has taken care of everything, no further processing is
needed. However, the only way to stop at raw_event is to return an error
(negative) value. Therefore, the processing is stopped at event instead.

c158c2afc9 HID: lenovo: Add support for Thinkpad X1 Tablet Thin keyboard
The Thinkpad X1 Tablet Thin keyboard's HID interface for the media-keys
and other special functions, is quite similar to the Thinkpad 10 ultrabook
keyboard's mouse/media-keys HID interface.

The only difference is that it needs a bit different key mappings.

Add support for the mute-LED and the non-standard media-keys on this
keyboard by re-using the tp10_ultrabook_kbd code combined with a new
lenovo_input_mapping_x1_tab_kbd() function.

2d0f1c071a HID: lenovo: Rework how the tp10ubkbd code decides which USB interface to use
Instead of looking for a hdev with a type of HID_TYPE_USBMOUSE find
the interface for the mute/mic-mute/fn-lock LEDs by checking for the
output-report which is used to set them.

This is a preparation patch for adding support for the LEDs on the
X1 tablet thin keyboard which uses the same output-report, but has
a separate (third) USB interface for the touchpad/mouse functionality.

e2da5ff435 HID: lenovo: Set default_triggers for the mute and micmute LEDs
The mute and mic-mute LEDs should be automatically turned on/off based
on the audio-card's mixer settings.

Add the standardized default-trigger names for this, so that the alsa
code can turn the LEDs on/off as appropriate (on supported audio cards).

This brings the mute/mic-mute LED support inline with the thinkpad_acpi
support for the same LEDs in keyboards directly connected to the
laptop's embedded-controller.

617103246c HID: lenovo: Map mic-mute button to KEY_F20 instead of KEY_MICMUTE
Mapping the mic-mute button to KEY_MICMUTE is technically correct but
KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X,
which does not fit in 8 bits, so it does not work.

Because of this userspace is expecting KEY_F20 instead,
theoretically KEY_MICMUTE should work under Wayland but even
there it does not work, because the desktop-environment is
listening only for KEY_F20 and not for KEY_MICMUTE.

The HID lenovo probe function only attaches drvdata to one of the

to which hid-lenovo is bound.

This allows a malicious device to fake being a device handled by

special handling (and thus dereferences hid_get_drvdata()) on another

Add a check for hid_get_drvdata() returning NULL, avoiding this

On Surface Laptops 1 and 2, this interface is used to connect the
integrated keyboard.

Note that this subsystem interface essentially provides a limited HID
transport layer. In contrast to the generic HID interface (TC=0x15) used
on newer Surface models, this interface only allows (as far as we know)
for a single device to be connected and is otherwise severely limited in
terms of support for feature- and output-reports. Specifically, only
caps-lock-LED output-reports and a single read-only feature-report are
supported.

for each volume key press. This patch adds a quirk to hid-plantronics

it happens within 5 ms from the last one that was handled.

The patch was tested on the mentioned model only, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected, because the
rate is about 3 times per second, which is far less frequent than once
in 5 ms.

434f77092e HID: logitech-dj: Handle newer quad/bt2.0 receivers in HID proxy mode
The Dinovo Edge and Dinovo Mini keyboards with builtin touchpad come with
a different version of the quad/bt2.0 combo receivers shipped with the
MX5000 and MX5500 keyboards. These receivers are compatible with one
another, e.g. the Dinovo Edge keyboard can be paired with the MX5000
receiver.

Like the MX5x00 receivers in HID proxy mode these receivers present
themselves as a hub with multiple USB-HID devices, one for the keyboard
and one for the mouse.

Where they differ is that the mouse USB-device has 2 input reports for
reporting mice events. It has the exact same INPUT(2) report as the
MX5x00 receivers, but it also has a second INPUT(5) mouse report which
is different; and when the Dinovo receivers are paired with the Dinovo
keyboards the second INPUT(5) mouse report is actually used for events
on the builtin touchpad.

Add support for handling the Dinovo quad/bluetooth-2.0 combo receivers
in HID proxy mode to logitech-dj, like we already do for the similar
MX5000 and MX5500 receivers.

This adds battery monitoring functionality (through logitech-hidpp) and
fixes the Phone (Fn + F1) and "[A]" - "[D]" (Fn + F9 - F12) hotkeys not
working on the Dinovo Edge.

Note these receivers present themselves as a hub with 2 separate USB
devices for the keyboard and mouse; and the logitech-dj code needs to
bind to both devices (just as with the MX5x00 receivers).

88f38846bf HID: wacom: Ignore attempts to overwrite the touch_max value from HID
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.

b7c20f3815 HID: ite: Enable QUIRK_TOUCHPAD_ON_OFF_REPORT on Acer Aspire Switch 10E
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.

fab3a95654 HID: logitech-dj: add support for the new lightspeed connection iteration
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 :(

fc6a31b007 HID: i2c-hid: Add I2C_HID_QUIRK_NO_IRQ_AFTER_RESET for ITE8568 EC on Voyo 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.
[ 3701.059717] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3707.205944] i2c_hid i2c-ITE8568:00: failed to reset device.
[ 3708.227940] i2c_hid i2c-ITE8568:00: can't add hid device: -61
[ 3708.236518] i2c_hid: probe of i2c-ITE8568:00 failed with error -61

Which leads to a significant boot delay.

df7b622906 HID: google: Get HID report on probe to confirm tablet switch state
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.

7c7d7ac7ce HID: hid-input: avoid splitting keyboard, system and consumer controls
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.

179e8e47c0 HID: wacom: Correct NULL dereference on AES pen proximity
The recent commit to fix a memory leak introduced an inadvertant NULL
pointer dereference. The `wacom_wac->pen_fifo` variable was never
intialized, resuling in a crash whenever functions tried to use it.
Since the FIFO is only used by AES pens (to buffer events from pen
proximity until the hardware reports the pen serial number) this would
have been easily overlooked without testing an AES device.

This patch converts `wacom_wac->pen_fifo` over to a pointer (since the
call to `devres_alloc` allocates memory for us) and ensures that we assign
it to point to the allocated and initalized `pen_fifo` before the function
returns.

c7aa374e00 HID: multitouch: Set to high latency mode on suspend.
Per Windows Precision Touchpad guidelines:

> The latency mode feature report is sent by the host to a Windows
> Precision Touchpad to indicate when high latency is desirable for
> power savings and, conversely, when normal latency is desired for
> operation.
>
> For USB-connected Windows Precision Touchpads, this enables the device
> to disambiguate between being suspended for inactivity (runtime IDLE)
> and being suspended because the system is entering S3 or Connected
> Standby.

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

Palm ejection stops working on some Elan and Synaptics touchpad after
commit 40d5bb8737 ("HID: multitouch: enable multi-input as a quirk for
some devices").

The commit changes the mt_class from MT_CLS_WIN_8 to
MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied
anymore.

So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is
essentially MT_CLS_WIN_8.

239319670e HID: hid-sensor-custom: Add custom sensor iio support
Currently custom sensors properties are not decoded and it is up to
user space to interpret.

Some manufacturers already standardized the meaning of some custom sensors.
They can be presented as a proper IIO sensor. We can identify these sensors
based on manufacturer and serial number property in the report.

This change is identifying hinge sensor when the manufacturer is "INTEL".
This creates a platform device so that a sensor driver can be loaded to
process these sensors.

b33752c300 HID: i2c-hid: Reorganize so ACPI and OF are separate modules
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.
