Input: wacom - enhance Wireless Receiver battery reporting
- Reports the current status of the battery (discharging, charging, full). - Also notify the upower daemon when there is a change in the battery value. - keep the battery value as a percentage, not the raw value - add WACOM_QUIRK_BATTERY to easily add a battery to a device (required for Bluetooth devices) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Przemo Firszt <przemo@firszt.eu> Acked-by: Ping Cheng <pingc@wacom.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
