Since those don't come from spi-peripheral-props, not really the correct
justification (although why they don't, I'm not sure). If you still saw
dtbs_check complaints after the first patch, I maybe the controller
schema is missing a reference to spi-controller.yaml?

I changed the first patch as suggested:
