The i2c one came from an Dell XPS13. The ALPS one I can't remember but highly

We simply don't have enough space on those touchpads to have an area carved
out for horizontal scrolling. Given that horizontal scrolling is rarely needed
anyway users of these touchpads will just have to cling to scroll bars or use
two-finger scrolling.
Exception are small clickpads because they already have an area blocked off
for software buttons and those small clickpads generally come from a time when
clickfinger wasn't much of a thing yet.

10s is not enough when running the test suite in parallel as any test may have
to wait longer than that to get access to the udev lock. Especially for
tests with multiple timeouts it was too easy to trigger timeouts.
Up the timeout to 30s, this seems reliable enough now.

Increase the mm move threshold for 3 and 4 finger gestures to 2 and 3 mm,
respectively. In multi-finger gestures it's common to have minor movement
while all fingers are being put down or before the conscious movement starts.
This can trigger invalid gesture detection (e.g. a pinch instead of a swipe).
Increase the movement threshold to make sure we have sufficient input data.
No changes to 2-finger movements.

Move mode control to libinput. This reduces some flexibility on what we can do
with modes but makes it a lot easier for anyone to implement modes correctly
and have the LEDs apply appropriately, etc. Let's go with the option to make
the 95% use-case easy. Note: whether the mode is actually used is up to the
caller, e.g. under Windows and OS X the mode only applies to the
rings/strips, not the buttons.
A tablet pad has 1 or more mode groups, all buttons/ring/strips are assigned
to a mode group. That group has a numeric mode index and is hooked to the
LEDs. libinput will switch the LEDs accordingly.
The mode group is a separate object. This allows for better APIs when it comes
to:
* checking whether a button/ring/strip is part of a mode group
* checking whether a button will trigger a mode transition
and in the future potentially:
* checking which mode transition will happen
* setting which button should change the mode transition
* changing what type of mode transition should happen.
* moving a button from one mode group to the other
This patch adds the basic scaffolding, without any real implementation.

The removal of the hysteresis even on precise touchpads has led to
difficulties controlling the cursor in a few instances. Since 27078b2667
we only have the hysteresis on Apple touchpads and the Lenovo *40 series and
later. Even on those do we see some positioning difficulties (bug 94379).
So restore the hysteresis by default again for all touchpads. In the future a
knob could be exposed for precision vs reactivity or something, but for now
the drawback of imprecise positioning does not outweigh the benefits we get
on those few devices.

This avoids accidental palm detection during two-finger scrolling if one
finger is inside the edge exclusion zone.
Palm detection is designed to avoid accidental touches while typing. If a
non-palm finger is on the touchpad already the user is unlikely to be typing.
So stop palm detection in this case and process the fingers as normal.
This implementation has a minor bug: if both palm touches start within the
palm exclusion zone within the same frame, neither will be labelled as palm
due to how we check the other touches. Since this is an extremeley niche case
we can live with that.

A large part of the bugs seen right now are related to touchpads jittering too
much. Fixing them one by one is entertaining, but time consuming. Right now
the number of touchpads that require a hysteresis seem to outnumber those that
don't, so switch the approach around: leave the hysteresis in place but
disable it for those touchpads that don't need it.

Make sure that the tool is valid while the event is valid, even if the device
gets destroyed before the event is destroyed.
This cannot actually be triggered right now, the event has a ref to the device
and the tools do not get removed until the device is destroyed. But for future
implementations (e.g. where the tool is otherwise automatically destroyed on
proximity out) we need to ensure the tool remains valid for the event
lifetime.

This interface handles the buttons on the physical tablet itself, including
the touch ring and the strip.
A notable difference to other libinput interfaces here is that we do not use
linux/input.h event codes for buttons. Instead, the buttons are merely
numbered sequentially, starting at button 1. This means:
* the API is different, instead of get_button() we have get_button_number() to
drive the point home
* there is no seat button count. pads are inherently different devices and
compositors should treat them as such. The seat button count makes sense
when you want to know how many devices have BTN_LEFT down, but it makes no
sense for buttons where all the semantics are handled by the compositor
anyway.
