38 Phandle to syscon block which provide access to System Reset Controller
48 This property is required only if the rpmsg/virtio functionality is used.
49 List of <&phandle type channel> - 1 channel for TX, 1 channel for RX, 1 channel for RXDB.
50 (see mailbox/fsl,mu.yaml)
56 If present, a phandle for a reserved memory area that used for vdev buffer,
57 resource table, vring region and others used by remote processor.
65 $ref: /schemas/types.yaml#/definitions/flag
67 Indicate whether need to load the default firmware and start the remote
68 processor automatically.
