USB HID core now shares its fwnode with its child HID device.
Since there can only be one HID device on a USB interface, it is redundant
to specify a hid node under the USB device. This allows usb HID device
drivers to be described in firmware and make use of device properties.

* [PATCH v8 0/3] Firmware Support for USB-HID Devices and CP2112
From: Danny Kaehn @ 2023-02-27 14:07 UTC (permalink / raw)
  To: robh+dt, krzysztof.kozlowski+dt, jikos, benjamin.tissoires
  Cc: bartosz.golaszewski, andriy.shevchenko, dmitry.torokhov,
	devicetree, linux-input, ethan.twardy

This patchset allows USB-HID devices to have DeviceTree bindings through sharing
the USB fwnode with the HID driver, and adds such a binding and driver
implementation for the CP2112 USB to SMBus Bridge (which necessitated the
USB-HID change). This change allows a CP2112 permanently attached in hardware to
be described in DT and interoperate with other drivers.

Thanks to all for your patience in working with me on these! I'll have
many lessons learned for future submissions.

Changes in v8:
- Apply Review tags retroactively to patches previously reviewed

Changes in v7:
- Use dev_fwnode when calling fwnod_handle_put in i2c_adapter in hid-cp2112.c
- Capitalize I2C and GPIO in commit message for patch 0003

Changes in v6:
- Fix fwnode_handle reference leaks in hid-cp21112.c
- Simplify hog node pattern in silabs,cp2112.yaml

Changes in v5:
 - Use fwnode API instead of of_node api in hid-core.c and hid-cp2112.c
 - Include sda-gpios and scl-gpios in silabs,cp2112.yaml
 - Additional fixups to silabs,cp2112.yaml to address comments
 - Submit threaded interrupt bugfix separately from this patchset, as requested

Changes in v4:
 - Moved silabs,cp2112.yaml to /Documentation/devicetree/bindings/i2c

Changes in v3:
 - Additional fixups to silabs,cp2112.yaml to address comments

Changes in v2:
 - Added more detail to silabs,cp2112.yaml dt-binding
 - Moved silabs,cp2112.yaml to /Documentation/devicetree/bindings/input
 - Added support for setting smbus clock-frequency from DT in hid-cp2112.c
 - Added freeing of of_nodes on error paths of _probe in hid-cp2112.c

* [PATCH v8 1/3] dt-bindings: i2c: Add CP2112 HID USB to SMBus Bridge
From: Danny Kaehn @ 2023-02-27 14:07 UTC (permalink / raw)

In-Reply-To: <20230227140758.1575-1-kaehndan@gmail.com>

This is a USB HID device which includes an I2C controller and 8 GPIO pins.

The binding allows describing the chip's gpio and i2c controller in DT
using the subnodes named "gpio" and "i2c", respectively. This is
intended to be used in configurations where the CP2112 is permanently
connected in hardware.

Second rule of acceptance for stable patches:

 - It cannot be bigger than 100 lines, with context.

Clearly not met here.

To me, this commit is something distributions may want to backport if
their users run are likely to run the affected hardware. But it's out
of scope for stable kernel branches.

As the snvs pwrkey will be moved to input/misc dir, the build config for
snvs pwrkey also changed to follow the format in input/misc: INPUT_SNVS_PWRKEY.
defconfig need to be updated to align with this change.

snvs pwrkey is not a traditional keyboard device,
more sense to move it into input/misc as other
pwrkey drivers.

From: Allen Ballway <ballway@chromium.org>

[ Upstream commit a2f416bf062a38bb76cccd526d2d286b8e4db4d9 ]

Certain touchscreen devices, such as the ELAN9034, are oriented
incorrectly and report touches on opposite points on the X and Y axes.
For example, a 100x200 screen touched at (10,20) would report (90, 180)
and vice versa.

This is fixed by adding device quirks to transform the touch points
into the correct spaces, from X -> MAX(X) - X, and Y -> MAX(Y) - Y.

* [PATCH v2] HID: apple: Set the tilde quirk flag on the Geyser 4 and later
From: Alex Henrie @ 2023-02-27  3:06 UTC (permalink / raw)
  To: linux-input, jkosina; +Cc: Alex Henrie

I recently tested several old MacBooks and as far as I can tell, all
MacBooks that have an ISO keyboard have the tilde key quirk:

Product    Model  Year  System      CPU    Shape  Labels     Country  Quirky
============================================================================
05ac:021b  A1181  2006  MacBook2,1  T5600  ISO    British    13       Yes
05ac:021b  A1181  2007  MacBook2,1  T7200  ISO    Québécois  13       Yes
05ac:0229  A1181  2007  MacBook4,1  T8300  ANSI   Usonian    33       No
05ac:022a  A1181  2007  MacBook4,1  T8100  ISO    English    13       Yes
05ac:022a  A1181  2007  MacBook5,2  P7350  ISO    Québécois  13       Yes
05ac:0237  A1278  2008  MacBook5,1  P7350  ISO    Dutch      13       Yes
05ac:0237  A1278  2009  MacBook5,5  P7550  ISO    British    13       Yes

The model number and year are from the laptop case. Since Apple printed
the same model and year on many different laptops, the system name (as
reported in the SMBIOS tables) and CPU form a more precise identifier.

* [PATCH AUTOSEL 6.1 22/58] HID: uclogic: Add support for XP-PEN Deco Pro MW
From: Sasha Levin @ 2023-02-27  2:04 UTC (permalink / raw)
  To: linux-kernel, stable
  Cc: José Expósito, Andreas Grosse, Jiri Kosina, Sasha Levin,

In-Reply-To: <20230227020457.1048737-1-sashal@kernel.org>

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit 9266a88156d1fbb8e50d6eeff7bac44ad4eaecc2 ]

The XP-PEN Deco Pro MW is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse. Its pen has 2 buttons, supports tilt and
pressure.

It can be connected using a USB cable or, to use it in wireless mode,
using a USB Bluetooth dongle. When it is connected in wireless mode the
device battery is used to power it.

All the pieces to support it are already in place. Add its ID and
quirks in order to support the device.

* [PATCH] HID: intel-ish-hid: ipc: Fix potential use-after-free in work function
From: Reka Norman @ 2023-02-27  2:49 UTC (permalink / raw)
  To: Srinivas Pandruvada
  Cc: Reka Norman, Benjamin Tissoires, Jiri Kosina, Li Qiong,
	linux-input, linux-kernel

When a reset notify IPC message is received, the ISR schedules a work
function and passes the ISHTP device to it via a global pointer
ishtp_dev. If ish_probe() fails, the devm-managed device resources
including ishtp_dev are freed, but the work is not cancelled, causing a
use-after-free when the work function tries to access ishtp_dev. Use
devm_work_autocancel() instead, so that the work is automatically
cancelled if probe fails.

* [PATCH AUTOSEL 5.10 03/19] HID: Add Mapping for System Microphone Mute

  To: linux-kernel, stable
  Cc: Jingyuan Liang, Dmitry Torokhov, Jiri Kosina, Sasha Levin, jikos,

In-Reply-To: <20230227020957.1052252-1-sashal@kernel.org>

From: Jingyuan Liang <jingyliang@chromium.org>

[ Upstream commit 2d60f9f4f26785a00273cb81fe60eff129ebd449 ]

HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.

Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.

* [PATCH AUTOSEL 5.15 10/25] HID: multitouch: Add quirks for flipped axes

  Cc: Allen Ballway, Jiri Kosina, Sasha Levin, jikos,
	benjamin.tissoires, groeck, alistair, dmitry.torokhov, jdelvare,
	jk, Jonathan.Cameron, cmo, u.kleine-koenig, linux-input
In-Reply-To: <20230227020855.1051605-1-sashal@kernel.org>

From: Allen Ballway <ballway@chromium.org>

[ Upstream commit a2f416bf062a38bb76cccd526d2d286b8e4db4d9 ]

Certain touchscreen devices, such as the ELAN9034, are oriented
incorrectly and report touches on opposite points on the X and Y axes.
For example, a 100x200 screen touched at (10,20) would report (90, 180)
and vice versa.

This is fixed by adding device quirks to transform the touch points
into the correct spaces, from X -> MAX(X) - X, and Y -> MAX(Y) - Y.

From: Bastien Nocera <hadess@hadess.net>

[ Upstream commit 498ba20690357691103de0f766960355247c78be ]

Don't stop and restart communication with the device unless we need to
modify the connect flags used because of a device quirk.

In-Reply-To: <20230227020045.1045105-1-sashal@kernel.org>

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit 14b71e6ad8ca59dd734c7fa9676f3d60bddee2a9 ]

The report descriptor used to get information about UGEE v2 devices is
incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame
is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of
type UCLOGIC_PARAMS_FRAME_MOUSE.

Here is the original report descriptor:

  0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00
                                     ^ This byte should be 2

Add a quirk to be able to fix the reported frame type.

Some UGEE v2 tablets have a wireless version with an internal battery
and their firmware is able to report their battery level.

However, there was not found a field on their descriptor indicating
whether the tablet has battery or not, making it mandatory to classify
such devices through the UCLOGIC_BATTERY_QUIRK quirk.

[ Upstream commit 7744ca571af55b794595cff2da9d51a26904998f ]

The XP-PEN Deco Pro SW is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse; however, the UCLOGIC_MOUSE_FRAME_QUIRK is
required because it reports an incorrect frame type. Its pen has 2
buttons, supports tilt and pressure.

It can be connected using a USB cable or, to use it in wireless mode,
using a USB Bluetooth dongle. When it is connected in wireless mode the
device battery is used to power it.

All the pieces to support it are already in place. Add its ID and
quirks in order to support the device.

* [PATCH AUTOSEL 6.1 19/58] HID: uclogic: Add frame type quirk
From: Sasha Levin @ 2023-02-27  2:04 UTC (permalink / raw)
  To: linux-kernel, stable
  Cc: José Expósito, Mia Kanashi, Andreas Grosse, Jiri Kosina,
	Sasha Levin, jikos, benjamin.tissoires, linux-input
In-Reply-To: <20230227020457.1048737-1-sashal@kernel.org>

From: José Expósito <jose.exposito89@gmail.com>

[ Upstream commit 14b71e6ad8ca59dd734c7fa9676f3d60bddee2a9 ]

The report descriptor used to get information about UGEE v2 devices is
incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame
is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of
type UCLOGIC_PARAMS_FRAME_MOUSE.

Here is the original report descriptor:

  0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00
                                     ^ This byte should be 2

Add a quirk to be able to fix the reported frame type.

* [PATCH AUTOSEL 6.1 07/58] HID: Add Mapping for System Microphone Mute

  To: linux-kernel, stable

In-Reply-To: <20230227020457.1048737-1-sashal@kernel.org>

From: Jingyuan Liang <jingyliang@chromium.org>

[ Upstream commit 2d60f9f4f26785a00273cb81fe60eff129ebd449 ]

HUTRR110 added a new usage code for a key that is supposed to
mute/unmute microphone system-wide.

Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE.
Additionally hid-debug is adjusted to recognize this keycode as well.
