From: Hans de Goede <hdegoede@redhat.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit f37c013409bb78ebb958821aa10d069e707cabac upstream.
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.
