Synaptics touchpad/trackpoint fail to work on Lenovo X1C5/6 and X280.
And they report they support intertouch mode through SMBus ver 3.
Current kernel driver limits RMI4 to SMBus 2.

Enable SMBus ver 3 and set them to SMBus mode will make synaptics work

[Test Case]
Tested on X1C5/6 and X280, confirm patches work fine.

[Regression Potential]
Enable RMI4 support on specific device ID, no regression is supposed.

Zesty and Xenial do not support this intertouch mode, so no need these

  UBUNTU: SAUCE: Input: synaptics - add Intertouch support on X1 Carbon
    6th and X280

Yiannis Marangos (2):
  UBUNTU: SAUCE: Input: synaptics-rmi4 - RMI4 can also use SMBUS version
  UBUNTU: SAUCE: Input: synaptics - Lenovo X1 Carbon 5 should use
