Each application/client 15 node would need a reference to at least a PRU node, and optionally define 16 some properties needed for hardware/firmware configuration. The below 17 properties are a list of common properties supported by the PRU remoteproc 18 infrastructure. 19 20 The application nodes shall define their own bindings like regular platform 21 devices, so below are in addition to each node's bindings. 22 23properties: 24 ti,prus: 25 $ref: /schemas/types.yaml#/definitions/phandle-array 26 description: phandles to the PRU, RTU or Tx_PRU nodes used 27 minItems: 1 28 maxItems: 6 29 items: 30 maxItems: 1 31 32 firmware-name: 33 $ref: /schemas/types.yaml#/definitions/string-array 34 minItems: 1 35 maxItems: 6 36 description: | 37 firmwares for the PRU cores, the default firmware for the core from 38 the PRU node will be used if not provided.
