Add properties to the Authenta SPI flash device node to enable access by
a UEFI application using a fixed GUID. Also specify that this device is
JEDEC compatible so that it is correctly initialized when running

Are we far enough along with part one of this series to talk about
getting these properties in the upstream binding document now?
You mean those bindings being part of the DT spec?
Yes, getting these added to
Documentation/devicetree/bindings/mtd/jedec,spi-nor.yaml in the kernel.
There is a related patch
[PATCH] dt-bindings: spi: Add YAML DT binding document for trivial devices
https://lore.kernel.org/all/20220407194936.223041-1-ma...@denx.de/
that didn't make it into the kernel yet.
Best regards
