HID++ 1.0 devices only export whether Fast Scrolling is enabled, not
whether they are capable of it. Reinstate the original quirks for the 3
supported mice so fast scrolling works again on those devices.

As talked about in the patch ("dt-bindings: HID: i2c-hid: goodix: Add
mainboard-vddio-supply") we may need to power up a 1.8V rail on the
host associated with touchscreen IO. Let's add support in the driver
for it.

In commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset line to
true state of the regulator"), we started tying the reset line of
Goodix touchscreens to the regulator.
The primary motivation for that patch was some pre-production hardware
(specifically sc7180-trogdor-homestar) where it was proposed to hook
the touchscreen's main 3.3V power rail to an always-on supply. In such
a case, when we turned "off" the touchscreen in Linux it was bad to
assert the "reset" GPIO because that was causing a power drain. The
patch accomplished that goal and did it in a general sort of way that
didn't require special properties to be added in the device tree for
homestar.
It turns out that the design of using an always-on power rail for the
touchscreen was rejected soon after the patch was written and long
before sc7180-trogdor-homestar went into production. The final design
of homestar actually fully separates the rail for the touchscreen and
the display panel and both can be powered off and on. That means that
the original motivation for the feature is gone.
There are 3 other users of the goodix i2c-hid driver in mainline.
I'll first talk about 2 of the other users in mainline: coachz and
mrbland. On both coachz and mrbland the touchscreen power and panel
power _are_ shared. That means that the patch to tie the reset line to
the true state of the regulator _is_ doing something on those
boards. Specifically, the patch reduced power consumption by tens of
mA in the case where we turned the touchscreen off but left the panel
on. Other than saving a small bit of power, the patch wasn't truly
necessary. That being said, even though a small bit of power was saved
in the state of "panel on + touchscreen off", that's not actually a
state we ever expect to be in, except perhaps for very short periods
of time at boot or during suspend/resume. Thus, the patch is truly not
necessary. It should be further noted that, as documented in the
original patch, the current code still didn't optimize power for every
corner case of the "shared rail" situation.
The last user in mainline was very recently added: evoker. Evoker is
actually the motivation for me removing this bit of code. It turns out
that for evoker we need to manage a second power rail for IO to the
touchscreen. Trying to fit the management of this IO rail into the
regulator notifiers turns out to be extremely hard. To avoid lockdep
splats you shouldn't enable/disable other regulators in regulator
notifiers and trying to find a way around this was going to be fairly
difficult.
Given the lack of any true motivation to tie the reset line to the
regulator, lets go back to the simpler days and remove the code. This
is, effectively, a revert of commit bdbc65eb77ee ("HID: i2c-hid:
goodix: Fix a lockdep splat"), commit 25ddd7cfc582 ("HID: i2c-hid:
goodix: Use the devm variant of regulator_register_notifier()"), and
commit 18eeef46d359 ("HID: i2c-hid: goodix: Tie the reset line to true
state of the regulator").

In certain circumstances, such as when creating I2C-connected HID
devices, we want to pass and retain some quirks (axis inversion, etc).
The source of such quirks may be device tree, or DMI data, or something
else not readily available to the HID core itself and therefore cannot
be reconstructed easily. To allow this, introduce "initial_quirks" field
in hid_device structure and use it when determining the final set of
quirks.
This fixes the problem with i2c-hid setting up device-tree sourced
quirks too late and losing them on device rebind, and also allows to
sever the tie between hid-code and i2c-hid when applying DMI-based
quirks.

The custom "debug" module parameter is fairly inflexible.
It can only manage debugging for all calls dbg_hid() at the same time.
Furthermore it creates a mismatch between calls to hid_dbg() which can
be managed by CONFIG_DYNAMIC_DEBUG and dbg_hid() which is managed by the
module parameter.
Furthermore the change to pr_debug() allows the debugging statements to
be completely compiled-out if desired.

It was reported that commit b300667b33b2 ("HID: amd_sfh: Disable the

x360.
Before this commit 3 sensors were reported, but they were not actually
functional. After this commit the sensors are no longer reported, but
also the resume time increased.
To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.
If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.
Disable hi-res scrolling on those devices until we implement scroll
events through HID++.

Add preliminary support for the Steam Deck's controller interface. Currently,
this only supports the controller inputs and toggling lizard mode (Valve's name
for a hardware kb/m emulation mode). It does not support any of the advanced
features, such as the motion sensors or force-feedback.
The Steam Deck also includes a heartbeat for lizard mode that switches it back
on if no reports have been received within a few milliseconds. The official
Steam client handles this by sending a handful of configuration reports every
few ms, so we copy this behavior by sending configuration reports to disable
the mouse and reset the digital mappings every 5ms. As this isn't needed for
the older Steam Controller, this is only done on the Steam Deck.

ambiguities
We currently have a struct ssam_request_sync and a function
ssam_request_sync(). While this is valid C, there are some downsides to
it.
One of these is that current Sphinx versions (>= 3.0) cannot
disambiguate between the two (see disucssion and pull request linked
below). It instead emits a "WARNING: Duplicate C declaration" and links
for the struct and function in the resulting documentation link to the
same entry (i.e. both to either function or struct documentation)
instead of their respective own entries.
While we could just ignore that and wait for a fix, there's also a point
to be made that the current naming can be somewhat confusing when
searching (e.g. via grep) or trying to understand the levels of
abstraction at play:
We currently have struct ssam_request_sync and associated functions
ssam_request_sync_[alloc|free|init|wait|...]() operating on this struct.
However, function ssam_request_sync() is one abstraction level above
this. Similarly, ssam_request_sync_with_buffer() is not a function
operating on struct ssam_request_sync, but rather a sibling to
ssam_request_sync(), both using the struct under the hood.
Therefore, rename the top level request functions:
ssam_request_sync() -> ssam_request_do_sync()
ssam_request_sync_with_buffer() -> ssam_request_do_sync_with_buffer()
ssam_request_sync_onstack() -> ssam_request_do_sync_onstack()

Similar to the target category (TC), the target ID (TID) can be one
value out of a small number of choices, given in enum ssam_ssh_tid.
In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text
expansion to, both, remove some textual clutter for the target category
values and enforce that the value belongs to the known set. Now that we
know the names for the target IDs, use the same trick for them as well.
Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

Previously, HID-BPF was relying on a bpf tracing program to be notified
when a program was released from userspace. This is error prone, as
LLVM sometimes inline the function and sometimes not.
So instead of messing up with the bpf prog ref count, we can use the
bpf_link concept which actually matches exactly what we want:
- a bpf_link represents the fact that a given program is attached to a
given HID device
- as long as the bpf_link has fd opened (either by the userspace program
still being around or by pinning the bpf object in the bpffs), the
program stays attached to the HID device
- once every user has closed the fd, we get called by
hid_bpf_link_release() that we no longer have any users, and we can
disconnect the program to the device in 2 passes: first atomically clear
the bit saying that the link is active, and then calling release_work in
a scheduled work item.
This solves entirely the problems of BPF tracing not showing up and is
definitely cleaner.

Avoid this by changing all HID client drivers to use 'depends on HID'.
For I2C_HID, this requires a larger rework of the Kconfig description,
but it hopefully becomes easier to understand without the complex
I2C_HID_CORE definition.

The bias for the gyroscope is not used correctly. The sensor bias
needs to be used in calculation of the 'sensivity' instead of being
an offset.
In practice this has little input on the values as the bias values
tends to be small (+/- 20).

Make sure calibration values are defined to prevent potential kernel

Some DualShock4 devices report invalid calibration data resulting
in kernel oopses due to division by zero during report handling.
The devices affected generally appear to be clone devices, which don't
implement all reports properly and don't populate proper calibration
data. The issue may have been seen on an official device with erased
calibration reports.
This patch prevents the crashes by essentially disabling calibration
when invalid values are detected.

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.

Since there is no valid I²C ID table provided, there is no

According to HUTRR39 logical sensor devices may be nested inside
physical collections or may be specified in multiple top-level
application collections (see page 59, strategies 1 and 2). However,
the current code was only recognizing those with physical collections.
This issue turned up in the T2 MacBook Pros which define the ALS in
a top-level application collection.

Commit b8a926bea8b1 ("kunit: Introduce KUNIT_EXPECT_MEMEQ and
KUNIT_EXPECT_MEMNEQ macros") introduced a new macro to compare blocks of
memory and, if the test fails, print the result in a human friendly
format. For example, this is the output of a test failure:
Expected res == params->expected, but
res ==
01 02 aa 00 00 00 03 bb 00 <00> 00 04 05
params->expected ==
01 02 aa 00 00 00 03 bb 00 <01> 00 04 05
Use this new macro to replace KUNIT_EXPECT_EQ + memcmp.

UGEEv2 tablets with battery can be connected using a USB cable or a USB
Bluetooth dongle.
When the Bluetooth dongle is used, the connection to that tablet can be
lost because the tablet is out of the range of the receiver or because
it was switched off using the switch placed in the back of the tablet's
frame.
After losing connection, the tablet is able to reconnect automatically
and its firmware sends a special packet indicating that the device was
reconnected. In response to this packet, the tablet needs to receive the
same array of magic data it expects on probe to enable its interfaces.
This patch implements a generic mechanism to hook raw events and
schedule a work to perform any custom action.

However, there was not found a field on their descriptor indicating
whether the tablet has battery or not, making it mandatory to classify

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
