From: Chris Bagwell <chris@xxxxxxxxxxxxxx> Reporting this will allow GUI config apps to correctly scale width sensitive config values (such as palm detect) to correct range. Current user apps are detecting kernels min/max=0/0 and making an assumption that it means 0/16 or 0/15. Synaptics touchpad interface guides show 4/15 are correct values but driver forces to 0 when no fingers on touchpad.
