Enabling trackpad in i2c mode, Tigerlake laptop

[Alder lake]

I have an I2C-HID trackpad. I checked from both windows device manager and linux.

Currently im only able to use ps2 mode, I want to enable i2c mode.

So Ive tried replacing Voodoops2 with Voodoo2c & voodoo2chid, i added the trackpad and keyboard in Device properties. And it still doesn't work.

For ssdt patches, ive tried SSDT-GPI0.aml and SSDT-XOSI.aml. I also tried using SSDTtime to create SSDT-XOSI.aml.

 

The keyboard and trackpad do appear under
IOService:/AppleACPIPlatformExpert/PC00@0/AppleACPIPCI/I2C0@15

IOService:/AppleACPIPlatformExpert/PC00@0/AppleACPIPCI/I2C1@15,1

 

but IOService:/IOResources/VoodooI2CServices only shows IOService:/IOResources/VoodooI2CServices/VoodooI2CLogger

 

The ioreg dump and my EFI folder is attached. Any suggestions would be helpful.

I'm fairly certain that VoodooI2C does not currently support tigerlake. At the very least, you'll have to add the I2C controller device ID to VoodooI2C's Info.plist. VoodooGPIO won't work without adding all the GPIO pin definitions and recompiling it. VoodooGPIO is only needed though for interrupts, so the trackpad could work in APIC or polling interrupts mode.
