This patch introduces a driver for the PixArt PS/2 touchpad, which supports both clickpad and touchpad types. At the same time, we extended the single data packet length to 16, because according to the current PixArt hardware and FW design, we need 11 bytes/15 bytes to represent the complete three-finger/four-finger data.
