[ 5.989588] psmouse serio1: synaptics: Your touchpad (PNP: TOS0213 PNP0f03) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org.
[ 6.039923] psmouse serio1: synaptics: Touchpad model: 1, fw: 9.32, id: 0x1e2a1, caps: 0xf00223/0x840300/0x12e800/0x52d884, board id: 3322, fw id: 2658004
The board is labelled TM3322.
Present on the Toshiba / Dynabook Portege X30-D and possibly others.
Confirmed working well with psmouse.synaptics_intertouch=1 and local build.

In mtk_pmic_keys_probe, the regs parameter is only set if the button is
parsed in the device tree. However, on hardware where the button is left
floating, that node will most likely be removed not to enable that
input. In that case the code will try to dereference a null pointer.
Let's use the regs struct instead as it is defined for all supported
platforms. Note that it is ok setting the key reg even if that latter is
disabled as the interrupt won't be enabled anyway.

The current implementation of the goodix_berlin driver lacks support for
revisions A and B of the Berlin IC. This change adds support for the
gt9897 IC, which is a Berlin-A revision part.
The differences between revision D and A are rather minor, a handful of
address changes and a slightly larger read buffer. They were taken from
the driver published by Goodix, which does a few more things that don't
appear to be necessary for the touchscreen to work properly.

Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).
In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.
Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.
Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.
As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.
We could not activly retest these devices because we no longer have them in
our archive, but based on the other old Clevo barebones we tested where the
new quirk had the same or a better behaviour I think it would be good to
apply it on these too.

Matrix keypads with high capacity need a longer settle time after
enabling all columns before re-enabling interrupts. The delay gives
the system time to settle and avoids spurious interrupts.
Add a new optional device property to configure the delay after
enabling all columns. The default is no delay.
