Ah yes I forgot the unevaluatedProperties didn't work properly,
sorry was running things on my DTs here with SPI and they were
all passing but of course I don't have Rob's fix to make the
unevaluatedProperties actually work.

Probably yeah include the spi properties yaml is a better
solution as that covers all the properties that might get used.

Thanks,
