f3c2b266b8 HID: elecom: Add support for ELECOM M-XT4DRBK (018E)
The 2025 revision of the left-handed EX-G wireless trackball
(M-XT4DRBK-G) reports USB ID 056e:018e instead of 056e:00fd. Its report
descriptor declares an 8-bit button field (Report Count 8) but only five
usages (Usage Maximum 5), so the sixth (Fn) button ends up as a
duplicate of button 5 and is unusable.

The report descriptor has the same layout as the M-XT3DRBK 018C
(button usage maximum at offset 16, button report count at 22, button
report size at 24, padding report size at 30), so reuse that fixup.

Rename the existing M_XT4DRBK define to M_XT4DRBK_00FD to match the
convention used for the other EX-G revisions.

Tested on a Raspberry Pi 5 with the same fixup in an
out-of-tree module on 6.12 (6.12.96+rpt-rpi-2712);
all six buttons are reported after the fix, and they
work (tested with xev as well).

Report descriptor as sent by the device, pre-fix (056e:018e,
215 bytes):

39e8e08571 HID: i2c-hid: add reset quirk for Lenovo Yoga Slim 7x Gen 11 keyboard
The ITE controller behind the keyboard of the Lenovo Yoga Slim 7x Gen 11
(048d:83db) carries out a reset but never raises the interrupt that
acknowledges it. i2c_hid_finish_hwreset() therefore waits out its full
one second timeout and logs "device did not ack reset within 1000 ms" on
every probe and every resume, before the keyboard comes up regardless.

Set I2C_HID_QUIRK_NO_IRQ_AFTER_RESET for it, as is already done for
several other ITE parts, so the reset is followed by a fixed 100 ms sleep
instead.

a9517958e8 HID: hid-msi: Add MSI Claw configuration driver
Adds configuration HID driver for the MSI Claw series of handheld PC's.
In this initial patch add the initial driver outline and attributes for
changing the gamepad mode, M-key behavior, and add a WO reset function.

Sending the SWITCH_MODE and RESET commands causes a USB disconnect in
the device. The completion will therefore never get hit and would trigger
an -EIO. To avoid showing the user an error for every write to these
attrs a bypass for the completion handling is introduced when timeout ==
0.

The initial version of this patch was written by Denis Benato, which
contained the initial reverse-engineering and implementation for the
gamepad mode switching. This work was later expanded by Zhouwang Huang
to include more gamepad modes. Finally, I refactored the drivers data
in/out flow and overall format to conform to kernel driver best
practices and style guides. Claude was used as an initial reviewer of
this patch.

663870a84c HID: hyperx: add driver for the HyperX QuadCast 2 mute button
The tap-to-mute button of the HyperX QuadCast 2 (03f0:07b4) is handled
entirely in the device firmware.  The firmware gates the audio internally
but never sends the Telephony "Phone Mute" usage (0x2f) that its own report
descriptor advertises, and it does not touch the UAC feature unit either.
Consequently neither an evdev key event nor an ALSA mixer change is ever
generated, and userspace has no way to learn that the microphone was muted:
desktops keep showing the microphone as live, and conferencing applications
keep displaying an unmuted microphone while transmitting silence.

The mute state is reported through a vendor-defined collection instead:

  06 c0 ff        Usage Page (Vendor-Defined 0xFFC0)
  a1 01           Collection (Application)
  06 c1 ff          Usage Page (Vendor-Defined 0xFFC1)
  85 77             Report ID (0x77)
  09 f0             Usage (0xF0)
  75 08  95 3f      Report Size (8), Report Count (63)
  81 02             Input (Data,Var,Abs)

Pressing the button emits a 64-byte report on that collection:

  77 06 00 00 ...   microphone unmuted
  77 06 01 00 ...   microphone muted

where byte 1 identifies the mute event and byte 2 carries the resulting
state.  As the payload is an opaque vendor blob carrying no HID usages,
hid-input cannot map it and a hwdb entry cannot express it either.

Add a driver that decodes the report and emits KEY_MICMUTE, which makes the
button behave like any other microphone mute key.

Note that the device reports the resulting absolute state, whereas
KEY_MICMUTE is a momentary key that userspace acts on as a toggle, so the
driver emits one keypress per state change.

Tested on a HyperX QuadCast 2 (03f0:07b4).

83e70ced0d HID: steelseries: Add support for Arctis Nova 5X and Nova 7 families
The Arctis Nova 5X, Nova 7 Gen2, and Nova 7 2026 refresh headsets answer
status polls, but also send unsolicited battery and connection updates
on a second HID interface (interface 5). Use that interface through
async_interface so the driver does not have to poll. Add request and
parse helpers for the Nova status format (0xb0/0xb7/0xb9/0xbb opcodes).

The original (pre-Gen2) Arctis Nova 7 family answers the same status
opcodes on the same interfaces, but reports battery capacity as a
discrete 0-4 level instead of a raw percentage. Add a second parse
function that maps that level through steelseries_map_capacity(), and a
separate device_info so the two capacity encodings cannot get mixed up.

Add the fourteen USB product IDs that share these protocols:

  0x2253  Arctis Nova 5X
  0x2202  Arctis Nova 7
  0x2206  Arctis Nova 7X
  0x22a4  Arctis Nova 7X (alternate PID)

2061075360 HID: asus: support the Zenbook A16 (UX3607OA) keyboard
The ASUS Zenbook A16 (UX3607OA), a Qualcomm Snapdragon X2 Elite Extreme
(Glymur)-based laptop, carries its main keyboard on an I2C-HID device
with the ID 0B05:4B42. Its Fn/media hotkeys are emitted as vendor-page
(HID_UP_ASUSVENDOR) usages on report 0x5A.

Match the device in hid-asus with the standard I2C keyboard quirks and
add the three usage mappings observed on the hardware:

  0x85 -> KEY_CAMERA  (Fn+F11, camera toggle)
  0x86 -> KEY_PROG1   (Fn+F12, MyASUS key)
  0x5f -> KEY_PROG2   (extra programmable key)

The camera-toggle key reports its usage (0x85) together with a companion
state byte in the same array report ("5a 85 01" / "5a 85 10"). The 0x10
companion aliases the brightness-down vendor usage and spuriously dims
the panel, so add QUIRK_FILTER_CAMERA_COMPANION to zero the companion
slots for this device before input mapping. The quirk is device-gated so
no other ASUS model is affected.

2346d6997b HID: steelseries: Add MSI Raider A18 HX A9WJG RGB support
The MSI Raider A18 HX A9WJG exposes two internal SteelSeries USB HID
devices for RGB lighting: KLC (1038:1122) for the keyboard and ALC
(1038:1161) for the lightbar/logo zones.

Add DMI-gated support for these devices and expose them as multicolor
LED class devices. The driver sends the same HID class SET_REPORT
control transfer as the tested userspace implementation for this
machine and writes a uniform RGB value to all known keyboard keys or
ALC zones.

The ALC payload uses sparse LED IDs on this chassis: 0x00, 0x01,
0x02 and 0x03 are physical zones, while 0x04 and 0x05 do not appear
to map to physical LEDs. Unused payload LED ID slots are initialized
to 0xff so they are ignored by the controller instead of defaulting
to LED ID 0x00.

Limit RGB support to USB interface 0 and the tested DMI system because
the KLC product ID is shared across MSI laptop designs and the key
layout mapping is model-specific. If the DMI or interface check does
not match, keep the device bound as a regular HID device instead of
failing probe.

Also make the existing Arctis 9 vendor usage-page check defensive by
returning false for report descriptors shorter than three bytes before
inspecting hdev->rdesc[0..2].

Tested on MSI Raider A18 HX A9WJG. Both internal SteelSeries ALC
(1038:1161) and KLC (1038:1122) HID devices bind on interface 0 and
create steelseries::lightbar and steelseries::kbd_backlight. Setting
multi_intensity and brightness changes the keyboard and lightbar
colors.

84910c459d HID: hid-oxp: Add OneXPlayer configuration driver
Adds OneXPlayer HID configuration driver. In this initial driver patch,
add the RGB interface for the first generation of HID based RGB control.

This interface provides the following attributes:
- brightness: provided by the LED core, this works in a fairly unique
  way on this device. The hardware accepts 5 brightness values (0-4),
  which affects the brightness of the multicolor and animated effects
  built into the MCU firmware. For monocolor settings, the device
  expects the hardware brightness value to be pushed to maximum, then we
  apply brightness adjustments mathematically based on % (0-100). This
  leads to some odd conversion as we need the brightness slider to reach
  the full range, but it has no affect when incrementing between the
  division points for other effects.
- multi-intensity: provided by the LED core for red, green, and blue.
- effect: Allows the MCU to set 19 individual effects.
- effect_index: Lists the 19 valid effect names for the interface.
- enabled: Allows the MCU to toggle the RGB interface on/off.
- enabled_index: Lists the valid states for enabled.
- speed: Allows the MCU to set the animation rate for the various
  effects.
- speed_range: Lists the valid range of speed (0-9).

The MCU also has a few odd quirks that make sending multiple synchronous
events challenging. It will essentially freeze if it receives another
message before it has finished processing the last command. It also will
not reply if you wait on it using a completion. To get around this, we
do a 200ms sleep inside a work queue thread and debounce all but the most
recent message using a 50ms mod_delayed_work. This will cache the last
write, queue the work, then return so userspace can release its write
thread. The work queue is only used for brightness/multi-intensity as
that is the path likely to receive rapid successive writes.

15a0449c95 HID: rakk: add support for Rakk Dasig X side buttons
The Rakk Dasig X gaming mouse has a faulty HID report descriptor that
declares USAGE_MAXIMUM=3 (buttons 1-3) while actually sending 5 button
bits (REPORT_COUNT=5). This causes the kernel to ignore side buttons
(buttons 4 and 5).

Fix by patching the descriptor to set USAGE_MAXIMUM=5 in the
report_fixup callback.

The mouse uses Telink vendor ID 0x248a with three product IDs for USB
direct (0xfb01), wireless dongle (0xfa02), and Bluetooth (0x8266)
connection modes. All three variants have the same bug at byte offset 17.

d69ccfcbc9 HID: hid-lenovo-go: Add Lenovo Legion Go Series HID Driver
Adds initial framework for a new HID driver, hid-lenovo-go, along with
attributes that report the firmware and hardware version for each
component of the HID device, of which there are 4 parts: The MCU, the
transmission dongle, the left "handle" controller half, and the right
"handle" controller half. Each of these devices are provided an attribute
group to contain its device specific attributes. Additionally, the touchpad
device attributes are logically separated from the other components in
another attribute group.

This driver primarily provides access to the configurable settings of the
Lenovo Legion Go and Lenovo Legion Go 2 controllers running the latest
firmware. As previously noted, the Legion Go controllers recently had a
firmware update[1] which switched from the original "SepentiaUSB" protocol
to a brand new protocol for the Go 2, primarily to ensure backwards and
forwards compatibility between the Go and Go 2 devices. As part of that
update the PIDs for the controllers were changed, so there is no risk of
this driver attaching to controller firmware that it doesn't support.
