Instead drop that sentence. Current driver support should not matter for
the bindings.

So you miss allOf: with $ref to spi props.

for simplicity's sake and for compatibility with the i2c devices already in use,
this driver does not have distinct 'compatible' properties for the i2c and spi
implementation.
this is why I just defined spi-max-frequency, used it in the spi example, but
not required it. just like in hsc030pa.yaml .

without a differentiation in the 'compatible' string I don't see how your request
can be implemented.

cheers,
peter

You cannot have different compatibles. I did not propose it. I wrote
nothing about compatible. I wrote about missing $ref in top-level for
spi-peripheral-props. Where do you see anything about compatible?

Best regards,

sorry, for one hot second I thought you want that property to be conditionally
defined, like

allOf:
  - $ref: /schemas/spi/spi-peripheral-props.yaml

  - if:
      properties:
        compatible:
          contains:
            const: honeywell,foo-spi
    then:
      properties:
        spi-max-frequency:
          maximum: 800000
      required:
        - spi-max-frequency

but I guess you only want the first two lines from here.

happy holidays,
peter

Yes, this one.
