/**
 * struct mbox_chan_ops - methods to control mailbox channels
 * @send_data:	The API asks the MBOX controller driver, in atomic
 *		context try to transmit a message on the bus. Returns 0 if
 *		data is accepted for transmission, -EBUSY while rejecting
 *		if the remote hasn't yet read the last data sent. Actual
 *		transmission of data is reported by the controller via
 *		mbox_chan_txdone (if it has some TX ACK irq). It must not
 *		sleep.
 * @flush:	Called when a client requests transmissions to be blocking but
 *		the context doesn't allow sleeping. Typically the controller
 *		will implement a busy loop waiting for the data to flush out.
 * @startup:	Called when a client requests the chan. The controller
 *		could ask clients for additional parameters of communication
 *		to be provided via client's chan_data. This call may
 *		block. After this call the Controller must forward any
 *		data received on the chan by calling mbox_chan_received_data.
 *		The controller may do stuff that need to sleep.
 * @shutdown:	Called when a client relinquishes control
