2017-02-12rules: Add extended evdev/input match rules for event nodes with the same nameHans de Goede
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.

2015-04-11udev: builtin-keyboard: add support for EVDEV_ABS_*Peter Hutterer
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.
