The reg property in both these nodes are used to identify which mixer is connected. We need to teach the sun8i-mixer driver to deal with an absent reg property first. ChenYu

Our display engine endpoints trigger some DTC warnings due to the fact that we're having a single endpoint that doesn't need any reg property, and since we don't have a reg property, we don't need the address-cells and size-cells properties anymore.
