Isn't stating that validation need against spi-controller.yaml as well as
this schema sufficient ? Can you please point an example how to make
controller binding a "subclass" of spi-controller.yaml binding ?

>Node name should be flash@0.

I think spi-controller.yaml uses wildcard for the name of a device node,
so anything in string@...value: should work.

Although just "spi-nor" also works, I agree to use "jedec, spi-nor" and drop
device name.
