I’m afraid the Rock 5A has a different SoC (an RK3588S vs the Rock Pi 4’s RK3399), so you can’t just apply my changes to the device trees and drivers. If you know your way around kernel drivers and device trees, maybe I can help point you in the right directon (although to be honest, I don’t remember much of the particulars any more; I mostly forget them and re-learn them when I have to).
