+- compatible: Must contain one or more of the following:
No, it can't contain more than one SoC specific value.
The text above does not say it can unless one is under the delusion
that, f.e. an r8a7790 SoC is also an r8a7791 SoC.
Hm, you're right. Sorry about my misunderstanding...
The only problem I'm still seeing with the current wording is that gen2/3
fallback
values are declared optional, while you can't get the driver to bind without
them on
the newer SoCs. But this is probably not a new problem...
If you would prefer an alternate wording please provide a suggestion.
Perhaps we should emphasize that the gen2/3 fallback values are mandatory?
