Michal Suchanek 38887d1bd5 rules: move input_id rule to a separate file
This places the input_id call after the evdev hwdb calls. With this the
hwdb fixups in evdev can affect the device capabilities assigned in
input_id.

Remove the ID_INPUT_KEY dependency in atkbd rule because it is now not
assigned at this point.

Hans de Goede 57bb707d48 rules: Add extended evdev/input match rules for event nodes with the same name
Sometimes a system may have 2 input event nodes with the same name where
we only want to apply keyboard hwdb rules to 1 of the 2 devices.

This problem happens e.g. on devices where the soc_button_array driver is
used (e.g. intel atom based tablets) which registers 2 event nodes with
the name "gpio-keys".

This commit adds a new extended match rule which extends the match to also
check $attr{phys} and $attr{capabilities/ev}, allowing to differentiate
between devices with an identical name.

Peter Hutterer 51c0c28698 udev: builtin-keyboard: add support for EVDEV_ABS_*
Parse properties in the form
EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>"

and apply them to the kernel device. Future processes that open that device
will see the updated EV_ABS range.

This is particularly useful for touchpads that don't provide a resolution in
the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974).

All values in the property are optional, e.g. a string of "::45" is valid to
set the resolution to 45.

The order intentionally orders resolution before fuzz and flat despite it
being the last element in the absinfo struct. The use-case for setting
fuzz/flat is almost non-existent, resolution is probably the most common case
we'll need.

To avoid multiple hwdb invocations for the same device, replace the
hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules
file. The new 60-evdev.rules is called for all event nodes
anyway, we don't need a separate rules file and second callout to the hwdb
builtin.
