Input: update input_mt_report_pointer_emulation to support hovering
For devices that are incapable of reporting per-contact distance and can only report ABS_DISTANCE, just distance is not enough for upper layers of OS to determine whether contact is leaving the area or if it is continuing hovering, we need BTN_TOOL_FINGER for that: Contact State Inactive Hovering Active (far away) (inside hover area) (touching surface) BTN_TOUCH 0 0 1 BTN_TOOL_FINGER 0 1 1 ABS_DISTANCE N/A 1 0 Signed-off-by:KT Liao <kt.liao@emc.com.tw> Signed-off-by:
