Keychron's C-series and K-series of keyboards copy the vendor and
product IDs of an Apple keyboard, but only behave like that device when
set to "Mac" mode. In "Windows" mode, the Fn key doesn't generate a
scancode, so it's impossible to use the F1-F12 keys when fnmode is set
to its default value of 1.
To fix this, make fnmode default to the new value of 3, which behaves
like fnmode=2 for Keychron keyboards and like fnmode=1 for actual Apple
keyboards. This way, Keychron devices are fully usable in both "Windows"
and "Mac" modes, while behavior is unchanged for everything else.

The (incorrect) "Pen" (0x02) application usage used in replacement
report descriptors throughout the drivers leads to all tablets
recognized as a "direct" input device (i.e. a tablet monitor) by
recent kernels, which messes up desktop environments [1].
Replace the application usage with "Digitizer" (0x01) for each
non-display graphics tablet.

Allow keyboard reports from interface #1 of Huion tablets to pass
unmodified, and stop the Wacom X.org driver from handling them.
The method for the latter is rather crude and also take the Dial reports
from the Wacom driver, but it's expected that libinput will be able to
handle them (still to be tested).
This enables Huion HS611 media and desktop keys.

The fbdev mmap function fb_mmap() unconditionally overrides the
driver's implementation if deferred I/O has been activated. This
makes it hard to implement mmap with anything but a vmalloc()'ed

This keyboard has two modes: regular HID and a native mode, which is used
in Windows driver. Native mode disables (poor) middle mouse button
scrolling emulation and reports middle button and scrolling events with a
custom report ID, which could be better handled in the driver.
This commit adds functional button mapping and native scrolling support.
HID collection in Bluetooth mode for custom report ID=5 is broken and
is patched upon connection. The collection initially contains incorrect
Usage Minimum/Usage Maximum numbers and, more importantly, marks Input
as Variable, not Array, while reporting values as in Array.
The keyboard is very similar to Compact USB/Bluetooth Keyboard with
TrackPoint, that's why this patch reuses all of cptkbd functions, except
for input mapping.

The third argument of usb_maxpacket(): in_out has been deprecated
because it could be derived from the second argument (e.g. using
usb_pipeout(pipe)).
N.B. function usb_maxpacket() was made variadic to accommodate the
transition from the old prototype with three arguments to the new one
with only two arguments (so that no renaming is needed). The variadic
argument is to be removed once all users of usb_maxpacket() get
migrated.

There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

Pull asm-generic updates from Arnd Bergmann:
"There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good.
This was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly tricky
and error-prone code. There is a small merge conflict against a
parisc cleanup, the solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel.
The hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks"

If HID_GROUP of eel is set to HID_GROUP_GENERIC, Whiskers Tablet Mode
Switch of eel hammer will not be detected by system because the
hid-vivaldi driver probes the device. When it is set to
HID_GROUP_VIVALDI, system will detect Whiskers Tablet Mode Switch
successfully and also support the vivaldi keyboard layout.

Add support to the hammer driver to parse vivaldi keyboard layouts and
expose them to userspace. This allows hammer devices to use vivaldi
function row keys while also supporting the other features this driver
supports, like the CBAS (chrome base attached switch) and a keyboard
backlight.

We need to support parsing the HID device in both the Vivaldi and the
Hammer drivers so that we can properly expose the function row physmap
to userspace when a hammer device uses a vivaldi keyboard layout for the
function row keys. Extract the feature mapping logic from the vivaldi
driver into an hid specific vivaldi library so we can use it from both
HID drivers.
To allow more code sharing we mandate that vivaldi data must be placed
at the very beginning of the driver data attached to the HID device
instance.

Let's introduce a common library file for the physmap show function
duplicated between three different keyboard drivers. This largely copies
the code from cros_ec_keyb.c which has the most recent version of the
show function, while using the vivaldi_data struct from the hid-vivaldi
driver. This saves a small amount of space in an allyesconfig build.

HID_QUIRK_INVERT is kind of complex to deal with and was bogus.
Furthermore, it didn't make sense to use a global per struct hid_device
quirk for something dynamic as the current state.
Store the current tool information in the report itself, and re-order
the processing of the fields to enforce having all the tablet "state"
fields before getting to In Range and other input fields.
This way, we now have all the information whether a tool is present
or not while processing In Range.
This new behavior enforces that only one tool gets forwarded to userspace
at the same time, and that if either eraser or invert is set, we enforce
BTN_TOOL_RUBBER.
Note that the release of the previous tool now happens in its own EV_SYN
report so userspace doesn't get confused by having 2 tools.
These changes are tested in the following hid-tools regression tests:

When a device exposes both Invert and InRange, Invert must be processed
before InRange. If we keep the order of the device and we process them
out of order, InRange will first set BTN_TOOL_PEN, and then Invert will
set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation,
but fixing it in the kernel is now easier.

Now that we have a list of fields/usages by priority order,
walk through that list to process the inputs instead of using the
order provided by the manufacturer.
Note that this changes the way we update the values in the struct
hid_field:
Previously, once a field was processed, we updated the new values.
Now we need to wait for the entire report to be processed to update
the values.
I don't think it will be an issue: because we were relying on the device
ordering, there were no guarantees to have a field stored before an other.
Which is why we introduced .report() in drivers to have those values
updated.

This will be used in a later commit:
we build a list of input fields (and usage_index) that is ordered based
on a usage priority.
Changing the usage priority allows to re-order the processed list, meaning
that we can enforce some usages to be process before others.
For instance, before processing InRange in the HID tablets, we need to
know if we are using the eraser (side or button). Enforcing a higher
(lower number) priority for Invert allows to force the input stack to
process that field before.
