This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

Revert "Input: bcm5974 - check endpoint type before starting traffic"
Input: xpad - add additional HyperX Controller Identifiers
Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

This patch intended to fix an well-knonw issue in old drivers where the
endpoint type is taken for granted, which is often triggered by fuzzers.
That was the case for this driver [1], and although the fix seems to be
correct, it uncovered another issue that leads to a regression [2], if
the endpoints of the current interface are checked.
The driver makes use of endpoints that belong to a different interface
rather than the one it binds (it binds to the third interface, but also
accesses an endpoint from a different one). The driver should claim the
interfaces it requires, but that is still not the case.
Given that the regression is more severe than the issue found by
syzkaller, the best approach is reverting the patch that causes the
regression, and trying to fix the underlying problem before checking
the endpoint types again.
Note that reverting this patch will probably trigger the syzkaller bug
at some point.
This reverts commit 2b9c3eb32a.

This should also work for IST3044B (though untested), however other

IST3032B) have a different format for coordinates, and they'd need

Another Fujitsu-related patch.
In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.
i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:3092) not working at all.
So this notebook uses a hid-over-i2c touchpad which is managed by the
i2c_designware input driver. Since you can't find a PS/2 mouse port on this
computer and you can't connect a PS/2 mouse to it even with an official
port replicator I think it's safe to not use the PS/2 mouse port at all.

When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.
The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

After commit 936e4d49ec ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") not only the getid command is skipped, but also
the de-activating of the keyboard at the end of atkbd_probe(), potentially
re-introducing the problem fixed by commit be2d7e4233 ("Input: atkbd -
fix multi-byte scancode handling on reconnect").
Make sure multi-byte scancode handling on reconnect is still handled
correctly by not skipping the atkbd_deactivate() call.

Now that the driver stores interrupt numbers corresponding to individual
GPIOs in non-clustered mode, it is possible to unify handling of both
modes by storing clustered interrupt at position 0 and setting the
number of interrupts in this case to 1.

There is no need to do conversion from GPIOs to interrupt numbers.
Convert row GPIOs to interrupt numbers once in probe() and use
this information when the driver needs to enable or disable given
interrupt line.

syzbot has found a type mismatch between a USB pipe and the transfer
endpoint, which is triggered by the bcm5974 driver[1].
This driver expects the device to provide input interrupt endpoints and
if that is not the case, the driver registration should terminate.
Repros are available to reproduce this issue with a certain setup for
the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in
the USB core after calling usb_submit_urb() with the following message:
"BOGUS urb xfer, pipe 1 != type 3"
Some other device drivers (like the appletouch driver bcm5974 is mainly
based on) provide some checking mechanism to make sure that an IN
interrupt endpoint is available. In this particular case the endpoint
addresses are provided by a config table, so the checking can be
targeted to the provided endpoints.
Add some basic checking to guarantee that the endpoints available match
the expected type for both the trackpad and button endpoints.
This issue was only found for the trackpad endpoint, but the checking
has been added to the button endpoint as well for the same reasons.
Given that there was never a check for the endpoint type, this bug has
been there since the first implementation of the driver (f89bd95c5c).

Add initial support for the new Goodix "Berlin" touchscreen ICs.
These touchscreen ICs support SPI, I2C and I3C interface, up to
10 finger touch, stylus and gestures events.
This initial driver is derived from the Goodix goodix_ts_berlin
available at [1] and [2] and only supports the GT9916 IC
present on the Qualcomm SM8550 MTP & QRD touch panel.
The current implementation only supports BerlinD, aka GT9916.
Support for advanced features like:
- Firmware & config update
- Stylus events
- Gestures events
- Previous revisions support (BerlinA or BerlinB)
is not included in current version.
The current support will work with currently flashed firmware
and config, and bail out if firmware or config aren't flashed yet.

The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck.
It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad,
volume buttons, a power button, and 2 LED ring lights.
The Legion Go firmware presents these controls as a USB hub with various
devices attached. In its default state, the gamepad is presented as an
Xbox controller connected to this hub. (By holding a combination of
buttons, it can be changed to use the older DirectInput API.)
This patch teaches the existing Xbox controller module `xpad` to bind to
the controller in the Legion Go, which enables support for the:
- directional pad,
- analog sticks (including clicks),
- X, Y, A, B,
- start and select (or menu and capture),
- shoulder buttons, and
- rumble.
The trackpad, touchscreen, volume controls, and power button are already
supported via existing kernel modules. Two of the face buttons, the
gyroscopes, rear paddles, and LEDs are not.
After this patch lands, the Legion Go will be mostly functional in Linux,
out-of-the-box. The various components of the USB hub can be synthesized
into a single logical controller (including the additional buttons) in
userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which
makes the Go fully functional.

The config HW_CONSOLE is always identical to the config VT and is not
visible in the kernel's build menuconfig. So, CONFIG_HW_CONSOLE is
redundant.
Replace all references to CONFIG_HW_CONSOLE with CONFIG_VT and remove
CONFIG_HW_CONSOLE.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So a -1 has been added when needed.

Some devices list 3 Gpio resources in the ACPI resource list for
the touchscreen:
1. GpioInt resource pointing to the GPIO used for the interrupt
2. GpioIo resource pointing to the reset GPIO
3. GpioIo resource pointing to the GPIO used for the interrupt
Note how the third extra GpioIo resource really is a duplicate
of the GpioInt provided info.
Ignore this extra GPIO, treating this setup the same as gpio_count == 2 &&
gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook
Colossus W803 rugged tablet and likely also on the CyberBook_T116K.

This driver does not use the SPI core as it should, instead tampering
with the SSP registers manually. Refactoring the driver is almost
certainly not worth it as the hardware seems to have been designed for
and used only in the HP iPAQ hx4700 removed more than a year ago in
d6df7df7ae ("ARM: pxa: remove unused board files"), so let's remove
it.
