[PATCH] mtd: spi-nor: add dt support for Everspin MRAMs

["Uwe Kleine-König" <u.kleine-koenig-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

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
