But that breaks systems with newer DTs on older kernels, which do not
know about sun7i-a20-mmc. I assume this somehow worked before(?), so why
not use:
compatible = "allwinner,sun7i-a20-mmc",
"allwinner,sun5i-a13-mmc";
So newer kernels would pick up the new name and behaviour, while older
kernels would revert to the old name and use the existing driver.
Cheers,
Andre.
