Trackpad Elan1000 I2C

[Daniil Somov]

Hello, my trackpad on an Asus x555uj laptop does not work. The fact is that it runs on the I2C bus (Elan 1000). Someone says that you need to patch GPIO, but I don't understand how it is at all. I'll leave the EFI file. Please, if you can help, I have started everything except the trackpad.

Sir, I added the SSDT-I2C1_STOP file to EFI, but I still haven't figured out how to register the patch in "Config.plist ACPI\Patch". Could you prescribe it for me?
