See patch 1 for more info on the motivations behind this. This is the best approach that I came up with with my limited knowledge of JSON schema. It has some limitations that are mentioned in patch 1. I don't know of any better ways to model this. Suggestions are welcome! Changes in v3: - s/slave/peripheral/g - Drop the | on description. - Drop the compatible property. Changes in v2: - Move other subnode properties listed in spi-controller.yaml to spi-slave-props.yaml - Move the Cadence controller-specific properties out of spi-slave-props.yaml. They will be added in a separate file. - Add a reference to spi-slave-props.yaml in spi-controller.yaml. - Update description.
