Derek J. ClarkandJiri Kosina a23f3497bf HID: hid-lenovo-go-s: Add Lenovo Legion Go S Series HID Driver
Adds initial framework for a new HID driver, hid-lenovo-go-s, along with
a uevent to report the firmware version for the MCU.

This driver primarily provides access to the configurable settings of the
Lenovo Legion Go S controller. It will attach if the controller is in
xinput or dinput mode. Non-configuration raw reports are forwarded to
ensure the other endpoints continue to function as normal.

Derek J. ClarkandJiri Kosina 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.

--
v6:
  - Make attributes static.
  - Use NULL instead of 0 in mcu_propery_out when there is no data.
v5:
  - Make version attributes static, retrieve them using delayed work
    during probe.
  - Fix endianness of version strings and print as hex.
v3:
  - Add hid-lenovo.c and Mark Pearson to LENOVO HID DRIVERS entry in MAINTAINERS

This patch adds support for handling the side buttons
on the RAPOO 0x2015 wireless mouse. These buttons were
previously not generating input events due to missing
driver logic.

The new code handles raw HID input report with Report
ID 1 and maps the side buttons to KEY_BACK and KEY_FORWARD
using the input subsystem.

Jiri Kosina 765b8aa0f7 Merge branch 'for-6.15/pidff' into for-linus
From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com>

This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.

This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.

No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.

I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)

With v8 and  tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.

I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.

Tomasz PakułaandJiri Kosina f06bf8d94f HID: Add hid-universal-pidff driver and supported device ids
Extend pidff compatibility, usable button range, manage pidff quirks and
set improved fuzz/flat default for high precision devices. Possibility
of fixing device descriptors in the future if such needs arises.

As many of PID devices are quite similar and not dependent on
custom drivers, this one can handle all of PID devices which
need special care.

Numerous sim racing/sim flight bases report a lot of buttons
in excess of 100. Moza Racing exposes 128 of them and thus
the need to extend the available range.

All the included devices were tested and confirmed working
with the help of the sim racing community.

Changes in v6:
- Support "split" devices with a separate "input device" for buttons
- Fixed comment styling

Charles WangandJiri Kosina 75e16c8ce2 HID: hid-goodix: Add Goodix HID-over-SPI driver
This patch introduces a new driver to support the Goodix GT7986U
touch controller. This device is not compatible with Microsoft's
HID-over-SPI protocol and therefore needs to implement its own
flavor. The data reported is packaged according to the HID
protocol but uses SPI for communication to improve speed. This
enables the device to transmit not only coordinate data but also
corresponding raw data that can be accessed by user-space programs
through the hidraw interface. The raw data can be utilized for
functions like palm rejection, thereby improving the touch experience.

Key features:
- Device connection confirmation and initialization
- IRQ-based event reporting to the input subsystem
- Support for HIDRAW operations (GET_REPORT and SET_REPORT)

but the kernel sees only 16 of 47 buttons on the throttle base.

This module enables all buttons, and also adds LED controls.

Button numbers 0 .. 63 on Orion2 are reserved for throttle grip;
the throttle base buttons have numbers 64 .. 110.

Linux kernel HID subsystem only supports up to 80 buttons.

Remap throttle base buttons to numbers 32 .. 78,
reserving only numbers 0 .. 31 for buttons on the grip handle.

Changes since v2:
   - Fixed automatic line wraps added by mail client

Changes since v1:
   - Fixed formatting of descriptor byte array;

Johannes RoithandJiri Kosina 740329d712 HID: mcp2200: added driver for GPIOs of MCP2200
Added a gpiochip compatible driver to control the 8 GPIOs of
the MCP2200 by using the HID interface.

Using GPIOs with alternative functions (GP0<->SSPND, GP1<->USBCFG,
GP6<->RXLED, GP7<->TXLED) will reset the functions, if set (unset by
default).

The driver was tested while also using the UART of the chip. Setting
and reading the GPIOs has no effect on the UART communication. However,
a reset is triggered after the CONFIGURE command. If the GPIO Direction
is constantly changed, this will affect the communication at low baud
rates. This is a hardware problem of the MCP2200 and is not caused by
the driver.

Benjamin TissoiresandJiri Kosina f5c27da4e3 HID: initial BPF implementation
Declare an entry point that can use fmod_ret BPF programs, and
also an API to access and change the incoming data.

A simpler implementation would consist in just calling
hid_bpf_device_event() for any incoming event and let users deal
with the fact that they will be called for any event of any device.

The goal of HID-BPF is to partially replace drivers, so this situation
can be problematic because we might have programs which will step on
each other toes.

For that, we add a new API hid_bpf_attach_prog() that can be called
from a syscall and we manually deal with a jump table in hid-bpf.

Whenever we add a program to the jump table (in other words, when we
attach a program to a HID device), we keep the number of time we added
this program in the jump table so we can release it whenever there are
no other users.

HID devices have an RCU protected list of available programs in the
jump table, and those programs are called one after the other thanks
to bpf_tail_call().

To achieve the detection of users losing their fds on the programs we
attached, we add 2 tracing facilities on bpf_prog_release() (for when
a fd is closed) and bpf_free_inode() (for when a pinned program gets
unpinned).
