Some devices need specific configuration or different defaults.
Push that into udev rules and a hwdb file, that's where detection is the
easiest. The LIBINPUT_MODEL_ prefix is used to determine some type of device
model. Note that this property is a private API and subject to change at
any time without notice.

The easiest way to get a device group is by looking at the phys path of the
input device (which looks like usb-0000:00:14.0-1/input1) and dropping the
/inputX bit. The rest is the same for devices that belong together (except on
the Cintiq 22HD Touch).
Ideally we could just take ATTRS{phys} but we can't select substrings to drop
into ENV so we need to do it ourselves. This patch adds a callout that takes a
syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP.
The rule triggers on any device that has a non-zero phys attribute, this
groups devices like tablets together but also devices like mice with multiple
interfaces.
