/**
* @page udev_config Static device configuration via udev
*
* libinput supports some static configuration through udev properties.
* These propertiesare read when the device is initially added
* to libinput's device list, i.e. before the @ref
* LIBINPUT_EVENT_DEVICE_ADDED event is generated.
*
* The following udev properties are supported:
* <dl>
* <dt>LIBINPUT_CALIBRATION_MATRIX</dt>
* <dd>Sets the calibration matrix, see
* libinput_device_config_calibration_get_default_matrix(). If unset,
* defaults to the identity matrix.</dd>
* <dt>ID_SEAT</dt>
* <dd>Assigns the physical seat for this device. See
* libinput_seat_get_physical_name(). Defaults to "seat0".</dd>
* <dt>WL_SEAT</dt>
* <dd>Assigns the logical seat for this device. See
* libinput_seat_get_logical_name()
* context. Defaults to "default".</dd>
* </dl>
*
* Below is an example udev rule to assign "seat1" to a device from vendor
* 0x012a with the model ID of 0x034b.
* @code
* ACTION=="add|change", KERNEL=="event[0-9]*", ENV{ID_VENDOR_ID}=="012a", \
* ENV{ID_MODEL_ID}=="034b", ENV{ID_SEAT}="seat1"
* @endcode
