+ * 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.
+ * @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 of a chan.
+ *              This call may block too. The controller must not forward
+ *              any received data anymore.
+ *              The controller may do stuff that need to sleep.
+ * @last_tx_done: If the controller sets 'txdone_poll', the API calls
+ *                this to poll status of last TX. The controller must
+ *                give priority to IRQ method over polling and never
+ *                set both txdone_poll and txdone_irq. Only in polling
+ *                mode 'send_data' is expected to return -EBUSY.
+ *                The controller may do stuff that need to sleep/block.
+ *                Used only if txdone_poll:=true && txdone_irq:=false
+ * @peek_data: Atomic check for any received data. Return true if controller
+ *                has some data to push to the client. False otherwise.
