Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt:

- compatible : May include a device-specific string consisting of the
               manufacturer and name of the chip. Bear in mind the DT binding
               is not Linux-only, but in case of Linux, see the "m25p_ids"
               table in drivers/mtd/devices/m25p80.c for the list of supported
               chips.
               Must also include "jedec,spi-nor" for any SPI NOR flash that can
               be identified by the JEDEC READ ID opcode (0x9F).

Hence it's OK.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
