    Input: byd - add BYD PS/2 touchpad driver · 98ee3771

    Driver for the BYD BTP10463 touchpad, found in PC Specialist `Lafite'
    laptops. This patch sends the magic command sequence which causes the
    touchpad to stream intellimouse-style packets.
    
    Gestures are detected inside the touchpad, and exposed as special
    values in the Z component of each packet - absolute coordinates are
    not supported, even in the Windows driver. At present, this supports
    two-finger vertical and horizontal scrolling, and provides the
    framework to expose the other gestures it can recognize.
