Introduction

------------

Currently the ALPS touchpad driver supports five protocol versions in use by

ALPS touchpads, called versions 1, 2, 3, 4 and 5.

Currently the ALPS touchpad driver supports seven protocol versions in use by

ALPS touchpads, called versions 1, 2, 3, 4, 5, 6 and 7.



Since roughly mid-2010 several new ALPS touchpads have been released and

 L:         Left button

 R / M:     Non-clickpads: Right / Middle button

            Clickpads: When > 2 fingers are down, and some fingers

            are in the button area, then the 2 coordinates reported

            are for fingers outside the button area and these report

            extra fingers being present in the right / left button

            area. Note these fingers are not added to the F field!

            so if a TWO packet is received and R = 1 then there are

            3 fingers down, etc.

 TWO:       1: Two touches present, byte 0/4/5 are in TWO fmt

            0: If byte 4 bit 0 is 1, then byte 0/4/5 are in MULTI fmt

               otherwise byte 0 bit 4 must be set and byte 0/4/5 are

               in NEW fmt

 F:         Number of fingers - 3, 0 means 3 fingers, 1 means 4 ...
