/**
 * struct mbox_client - User of a mailbox
 * @dev:                The client device
 * @tx_block:           If the mbox_send_message should block until data is
 *                      transmitted.
 * @tx_tout:            Max block period in ms before TX is assumed failure
 * @knows_txdone:       If the client could run the TX state machine. Usually
 *                      if the client receives some ACK packet for transmission.
 *                      Unused if the controller already has TX_Done/RTR IRQ.
 * @rx_callback:        Atomic callback to provide client the data received
 * @tx_prepare:         Atomic callback to ask client to prepare the payload
 *                      before initiating the transmission if required.
 * @tx_done:            Atomic callback to tell client of data transmission
