The MR25 family doesn't support JEDEC, so they need explicit mentioning
in the list of supported spi IDs. This makes it possible to add these
using for example:
compatible = "everspin,mr25h40";

Hello,
independent of the decision if -nonjedec is ok for m25p, this is needed
to make Everspin's MRAMs work.
Best regards
Uwe
