Ping Cheng dc9dc864f3 HID: wacom: set initial hardware touch switch state to 'off'
Wacom touch devices have two types of touch switches: softkey touch
toggle and hardware touch switch. For softkey toggle, we assume
touch is on by default in the driver. However the hardware touch
switch is controlled by end users. We don't know if it's on or off
before getting the status event.

This patch sets touch off for devices with a hardware switch until we
get the status. This is a bit safer for users who leave the switch "off"
and don't want any accidental touches. The tradeoff is a slight delay
between device connection and touch becoming enabled for users who
leave the switch "on".

The `input_mt_get_slot_by_key` function may return a negative value
if an error occurs (e.g. running out of slots). If this occurs we
should really avoid reporting any data for the slot.

Jason Gerecke 6ca2350e11 HID: wacom: Re-enable touch by default for Cintiq 24HDT / 27QHDT
Commit 670e90924b ("HID: wacom: support named keys on older devices")
added support for sending named events from the soft buttons on the
24HDT and 27QHDT. In the process, however, it inadvertantly disabled the
touchscreen of the 24HDT and 27QHDT by default. The
`wacom_set_shared_values` function would normally enable touch by default
but because it checks the state of the non-shared `has_mute_touch_switch`
flag and `wacom_setup_touch_input_capabilities` sets the state of the
/shared/ version, touch ends up being disabled by default.

This patch sets the non-shared flag, letting `wacom_set_shared_values`
take care of copying the value over to the shared version and setting
the default touch state to "on".

Uwe Kleine-König fc7a6209d5 bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

Douglas Anderson 18eeef46d3 HID: i2c-hid: goodix: Tie the reset line to true state of the regulator
The regulator for the touchscreen could be:
* A dedicated regulator just for the touchscreen.
* A regulator shared with something else in the system.
* An always-on regulator.

How we want the "reset" line to behave depends a bit on which of those
three cases we're in. Currently the code is written with the
assumption that it has a dedicated regulator, but that's not really
guaranteed to be the case.

The problem we run into is that if we leave the touchscreen powered on
(because someone else is requesting the regulator or it's an always-on
regulator) and we assert reset then we apparently burn an extra 67 mW
of power. That's not great.

Let's instead tie the control of the reset line to the true state of
the regulator as reported by regulator notifiers. If we have an
always-on regulator our notifier will never be called. If we have a
shared regulator then our notifier will be called when the touchscreen
is truly turned on or truly turned off.

Using notifiers like this nicely handles all the cases without
resorting to hacks like pretending that there is no "reset" GPIO if we
have an always-on regulator.

NOTE: if the regulator is on a shared line it's still possible that
things could be a little off. Specifically, this case is not handled
even after this patch:
1. Suspend goodix (send "sleep", goodix stops requesting regulator on)
2. Other regulator user turns off (regulator fully turns off).
3. Goodix driver gets notified and asserts reset.
4. Other regulator user turns on.
5. Goodix driver gets notified and deasserts reset.
6. Nobody resumes goodix.

With that set of steps we'll have reset deasserted but we will have
lost the results of the I2C_HID_PWR_SLEEP from the suspend path. That
means we might be in higher power than we could be even if the goodix
driver thinks things are suspended. Presumably, however, we're still
in better shape than if we were asserting "reset" the whole time. If
somehow the above situation is actually affecting someone and we want
to do better we can deal with it when we have a real use case.

The value chosen for the threshold, about 1.5 ~ 2 mm, is similar to the

The Magic Mouse, generations 1 and 2, doesn't have a physical scroll
wheel, instead, the REL_WHEEL and REL_HWHEEL events are emulated
when sliding a finger on the surface of the mouse.
However, the smooth movement of the finger is transformed into a step
based scroll on the screen, leading to a suboptimal user experience.

Emulate high-resolution scroll by sending REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES events so the scroll on the screen is closer to the
finger movement.

Dmitry Torokhov f4abaa9eeb HID: input: do not report stylus battery state as "full"
The power supply states of discharging, charging, full, etc, represent
state of charging, not the capacity level of the battery (for which
we have a separate property). Current HID usage tables to not allow
for expressing charging state of the batteries found in generic
styli, so we should simply assume that the battery is discharging
even if current capacity is at 100% when battery strength reporting
is done via HID interface. In fact, we were doing just that before
commit 581c448476.

This change helps UIs to not mis-represent fully charged batteries in
styli as being charging/topping-off.

Ye Xiang e48bf29cf9 HID: intel-ish-hid: use async resume function
ISH IPC driver uses asynchronous workqueue to do resume now, but there is
a potential timing issue: when child devices resume before bus driver, it
will cause child devices resume failed and cannot be recovered until
reboot. The current implementation in this case do wait for IPC to resume
but fail to accommodate for a case when there is no ISH reboot and soft
resume is taking time. This issue is apparent on Tiger Lake platform with
5.11.13 kernel when doing suspend to idle then resume(s0ix) test. To
resolve this issue, we change ISHTP HID client to use asynchronous resume
callback too. In the asynchronous resume callback, it waits for the ISHTP
resume done event, and then notify ISHTP HID client link ready.

Maximilian Luz 2b2bcc76e2 HID: surface-hid: Fix get-report request
Getting a report (e.g. feature report) from a device requires us to send
a request indicating which report we want to retrieve and then waiting
for the corresponding response containing that report. We already
provide the response structure to the request call, but the request
isn't marked as a request that expects a response. Thus the request
returns before we receive the response and the response buffer indicates
a zero length response due to that.

This essentially means that the get-report calls are broken and will
always indicate that a report of length zero has been read.

Fix this by appropriately marking the request.

Pascal Giard fb1a79a6b6 HID: sony: fix freeze when inserting ghlive ps3/wii dongles
This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU
USB dongle. Indeed, with the current implementation, inserting one of
those USB dongles will lead to a hard freeze. I apologize for not
catching this earlier, it didn't occur on my old laptop.

While the issue was isolated to memory alloc/free, I could not figure
out why it causes a freeze. So this patch fixes this issue by
simplifying memory allocation and usage.

We remind that for the dongle to work properly, a control URB needs to
be sent periodically. We used to alloc/free the URB each time this URB
needed to be sent.

With this patch, the memory for the URB is allocated on the probe, reused
for as long as the dongle is plugged in, and freed once the dongle is
unplugged.

Even Xu 4aae88b9a9 HID: intel-ish-hid: ishtp: Add dma_no_cache_snooping() callback
Different platforms have different DMA capability, on most of
platforms, DMA support cache snooping. But few platforms,
such as ElkhartLake (EHL), don't support cache snooping
which requires cache flush from driver.

So add a hardware level callback to let ishtp driver know if cache
flush is needed.

As most of platform support cache snooping, so driver will not
do cache flush by default, until platform implements this callback
and return true explicitly.

There is no need to use a quirk and then return -ENODEV from the

The hid-multitouch hiddev has a group of HID_GROUP_MULTITOUCH_WIN_8,

Hans de Goede 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.

Hans de Goede 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.

Benjamin Moody 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.

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

John Chen 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.

John Chen 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.

Hans de Goede 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.

Hans de Goede 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.

Hans de Goede 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.

Hans de Goede 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.

Without this the max_brightness sysfs-attribute will report 255 which is
wrong.

Hans de Goede 033c978680 HID: lenovo: Remove lenovo_led_brightness_get()
The led_classdev already contains a cached value of the last set
brightness, the brightness_get callback is only meant for LED drivers
which can read back the actual / current brightness from the hardware.

Since lenovo_led_brightness_get() just returns the last set value
it does not add any functionality, so we can just remove it.

Hans de Goede 34348a8661 HID: lenovo: Check hid_get_drvdata() returns non NULL in lenovo_event()
The HID lenovo probe function only attaches drvdata to one of the
USB interfaces, but lenovo_event() will get called for all USB interfaces
to which hid-lenovo is bound.

This allows a malicious device to fake being a device handled by
hid-lenovo, which generates events for which lenovo_event() has
special handling (and thus dereferences hid_get_drvdata()) on another
interface triggering a NULL pointer exception.

Add a check for hid_get_drvdata() returning NULL, avoiding this
possible NULL pointer exception.

Hans de Goede 658d04e6eb HID: lenovo: Fix lenovo_led_set_tp10ubkbd() error handling
Fix the following issues with lenovo_led_set_tp10ubkbd() error handling:

1. On success hid_hw_raw_request() returns the number of bytes sent.
   So we should check for (ret != 3) rather then for (ret != 0).

2. Actually propagate errors to the caller.

3. Since the LEDs are part of an USB keyboard-dock the mute LEDs can go
   away at any time. Don't log an error when ret == -ENODEV and set the
   LED_HW_PLUGGABLE flag to avoid errors getting logged when the USB gets
   disconnected.

The lenovo_led_brightness_set function may sleep, so we should have the

then the regular brightness_set callback.

When toggled through sysfs this is not a problem, but the brightness_set

Maximilian Luz 35a927f284 HID: surface-hid: Add support for legacy keyboard interface
Add support for the legacy keyboard (KBD/TC=0x08) HID transport layer of
the Surface System Aggregator Module (SSAM) to the Surface HID driver.
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.

On those models, the internal keyboard and touchpad (as well as some

generic HID subsystem (TC=0x15) of the Surface System Aggregator Module
(SSAM). This subsystem provides a generic HID transport layer, support
for which is implemented by this driver.

capability to take special actions when there is a change in the system
