HID: rapoo: Add support for side buttons on RAPOO 0x2015 mouse

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.

Tested on a RAPOO mouse with USB ID 24AE:2015.

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.

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

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)

WinWing Orion2 throttle works with Linux out of box,
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;
- Using product codes of Winwing grips in config.

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.

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).

hid: topre: Add driver fixing report descriptor

The Topre REALFORCE R2 firmware incorrectly reports that interface
descriptor number 1, input report descriptor 2's events are array events
rather than variable events. That particular report descriptor is used
to report keypresses when there are more than 6 keys held at a time.
This bug prevents events from this interface from being registered
properly, so only 6 keypresses (from a different interface) can be
registered at once, rather than full n-key rollover.

This commit fixes the bug by setting the correct value in a report_fixup
function.
