I just made my touchscreen/trackpad working. Here are my tips for those who are still struggling. They may not be helpful/correct for everyone, but at least for my case.
Computer model: HP Spectre X360 13t-ac000, Kaby Lake.
I2C Controller: pci8086 9d60, ELAN 0732
Steps:
1. Apply DSDT (partial hot) patch to Spoof OSX to Windows 2015
2. Exactly follow the GPIO pinning guide
3. Apply DSDT patch to enable GPIO controller
So far everything is mentioned in the installation guide.

Something different:
1. remove AppleIntelLpssI2CController.kext, AppleIntelLpssI2C.kext, AppleHPM.kext from S/L/E.
2. Put VoodooI2C.kext, VoodooI2CHID.kext in S/L/E, rather than Clover/kexts/Other, rebuild your cache. Otherwise, the I2C kexts would not be loaded, and occasionally can be loaded but get SSCN, FMCN not implemented error in the kernel log. Follow
https://voodooi2c.github.io/#Common Errors/Common Errors to check the kernel log.
Finally, there are VoodooPS2Controller.kext (enable keyboard/trackpad), VoodooI2C, VoodooI2CHID in my S/L/E, and none of them in Clover.
This is my first post in the forum, and give my credit to Alexandre Daoud for his awesome and magic work to make this happen!
