Wildcards are not allowed in compatibles. In filename wildcards or
family name could work if they are really going to match the devices. I
have doubts here. 67xx is quite a lot of different devices, so I am not
sure this will cover them all.
I would prefer one name (oldest SoC or lowest number).

Krzysztof
