    Input: Add INPUT_PROP_TOPBUTTONPAD device property · f37c0134
    Hans de Goede 提交于
    On some newer laptops with a trackpoint the physical buttons for the
    trackpoint have been removed to allow for a larger touchpad. On these
    laptops the buttonpad has clearly marked areas on the top which are to be
    used as trackpad buttons.
    
    Users of the event device-node need to know about this, so that they can
    properly interpret BTN_LEFT events as being a left / right / middle click
    depending on where on the button pad the clicking finger is.
    
    This commits adds a INPUT_PROP_TOPBUTTONPAD device property which drivers
    for such buttonpads will use to signal to the user that this buttonpad not
    only has the normal bottom button area, but also a top button area.
