/**
* 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.
* @send_controller_data:
* Send data for the controller driver. This could be data to
* configure the controller or data that may be cached in the
* controller and not transmitted immediately. There is no ACK
* for this request and the request is not buffered in the
* controller. 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.
