I recently managed to get my 7280 trackpad working using VoodooI2CHID with GPIO pinning so that it operates in interrupt mode, rather than polling mode. The issue is that I only got it to work with OpenCore 0.5.9, and gestures aren't working. I have a WIP to update to OpenCore 0.6.4, but so far I haven't managed to get the trackpad working yet. This means I'm also stuck on Catalina for now just like you and can't run Big Sur yet. I am attaching a scrubbed config.plist along with my ACPI .dsl files (will need to be compiled to .aml files in order to use them w/ OC), and I used the kext versions mentioned in the README.md file for my testing. Also, I have a Fenvi PCIe adapter so I'm not using itlwm for my WiFi. Other than that, maybe people here will find these files helpful? OpenCore_Dell-0.5.9.zip
