parentInput: synaptics - add Intertouch support on X1 Carbon 6th and X280 (diff)
Input: synaptics - add Lenovo 80 series ids to SMBus
This time, Lenovo decided to go with different pieces in its latest series of Thinkpads. For those we have been able to test: - the T480 is using Synaptics with an IBM trackpoint -> it behaves properly with or without intertouch, there is no point not using RMI4 - the X1 Carbon 6th gen is using Synaptics with an IBM trackpoint -> the touchpad doesn't behave properly under PS/2 so we have to switch it to RMI4 if we do not want to have disappointed users - the X280 is using Synaptics with an ALPS trackpoint -> the recent fixes in the trackpoint handling fixed it so upstream now works fine with or without RMI4, and there is no point not using RMI4 - the T480s is using an Elan touchpad, so that's a different story Cc: <stable@vger.kernel.org> # v4.14.x, v4.15.x, v4.16.x Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: KT Liao <kt.liao@emc.com.tw> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
