As title, I'v successfully  setup EFI with opencore 0.8.5 for a touchpad on Latitude 5510 working 

You have to use SSDTS attached and kexts attached, but you must disable  Voodooinput.kext, VoodooPS2Mouse.kex and VoodooPS2Trackpad.kext from VoodooPS2Controller kext as you can see on screenshoot.

You have to add to bootargs this string 

-vi2c-force-polling

Hope It Helps
