Each application/client15 node would need a reference to at least a PRU node, and optionally define16 some properties needed for hardware/firmware configuration. The below17 properties are a list of common properties supported by the PRU remoteproc18 infrastructure.19 20 The application nodes shall define their own bindings like regular platform21 devices, so below are in addition to each node's bindings.22 23properties:24 ti,prus:25 $ref: /schemas/types.yaml#/definitions/phandle-array26 description: phandles to the PRU, RTU or Tx_PRU nodes used27 minItems: 128 maxItems: 629 items:30 maxItems: 131 32 firmware-name:33 $ref: /schemas/types.yaml#/definitions/string-array34 minItems: 135 maxItems: 636 description: |37 firmwares for the PRU cores, the default firmware for the core from38 the PRU node will be used if not provided.
