As mentioned in my reply to the cover letter, this patch isn't needed. We ask people to add model-specific compatibles in the device tree in case the hardware turns out not to be so compatible with the old hardware we thought it was compatible with. With the model-specific compatible in place, we have a way out. Without it, we'd have to ask everyone to update their device trees, which annoys some people who'd like to have some sort of backward compatibility. If the model-specific + fallback compatibles combination was to be listed, the line would include both compatibles. But we're not doing that for Allwinner stuff. As mentioned it is there just in case. The best outcome is we don't care and don't need to use them. ChenYu
