I think we will also need more for child nodes:
patternProperties:
"^dac@[0-9a-f]+$":
type: object
additionalProperties: true
reg:
# add more rules for reg here
required:
- compatible
- reg
allOf:
- if:
not:
properties:
compatible:
contains:
- adi,axi-dac-ad3552r
then:
patternProperties:
"^dac@[0-9a-f]+$": false

Or use existing SPI bindings.
