Input: synaptics - set min/max for finger width
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.
