[Artful][linux-oem][PATCH 0/3] Enable synaptics touchpad intertouch support on

[Aaron Ma]

BugLink: http://bugs.launchpad.net/bugs/1723986

[Impact]
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.

[Fix]
Enable SMBus ver 3 and set them to SMBus mode will make synaptics work
fine.

[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
patches.
