+ * struct cec_msg - CEC message structure.
+ * @tx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
+ *		driver when the message transmission has finished.
+ * @rx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
+ *		driver when the message was received.
+ * @len:	Length in bytes of the message.
+ * @timeout:	The timeout (in ms) that is used to timeout CEC_RECEIVE.
+ *		Set to 0 if you want to wait forever. This timeout can also be
+ *		used with CEC_TRANSMIT as the timeout for waiting for a reply.
+ *		If 0, then it will use a 1 second timeout instead of waiting
+ *		forever as is done with CEC_RECEIVE.
+ * @sequence:	The framework assigns a sequence number to messages that are
+ *		sent. This can be used to track replies to previously sent
+ *		messages.
+ * @flags:	Set to 0.
+ * @msg:	The message payload.
+ * @reply:	This field is ignored with CEC_RECEIVE and is only used by
+ *		CEC_TRANSMIT. If non-zero, then wait for a reply with this
+ *		opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
+ *		a possible ABORT reply. If there was an error when sending the
+ *		msg or FeatureAbort was returned, then reply is set to 0.
+ *		If reply is non-zero upon return, then len/msg are set to
+ *		the received message.
+ *		If reply is zero upon return and status has the
+ *		CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
+ *		the received feature abort message.
+ *		If reply is zero upon return and status has the
+ *		CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
+ *		all. If reply is non-zero for CEC_TRANSMIT and the message is a
+ *		broadcast, then -EINVAL is returned.
+ *		if reply is non-zero, then timeout is set to 1000 (the required
+ *		maximum response time).
+ * @rx_status:	The message receive status bits. Set by the driver.
+ * @tx_status:	The message transmit status bits. Set by the driver.
+ * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
+ * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
+ * @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
+ *		driver.
+ * @tx_error_cnt: The number of 'Error' events. Set by the driver.

- * @gpio_base: The index number of the first GPIO assigned to this

- *             consecutively numbered gpios beginning at the given base,
- *             with the size of the block depending on the model of the
- *             expander chip.
- * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
- *                instead of as an oscillator, increasing the size of the
- *                GP(I)O pool created by this expander by one.  The
- *                output-only GPO pin will be added at the end of the block.
- * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
- *                 for each IO line in the expander.  Setting the bit at
- *                 position n will enable the pull-up for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
- *                 resistor for each IO line in the expander. Setting the
- *                 bit at position n will enable the pull-down for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
- *                     operation for each IO line in the expander. Setting the
- *                     bit at position n enables open-drain operation for
- *                     the IO at the corresponding offset.  Clearing the bit
- *                     enables regular push-pull operation for that IO.
- *                     For chips with fewer than 16 IO pins, high-end bits
- *                     are ignored.
- * @io_polarity: A bit-mask which enables polarity inversion for each IO line
- *               in the expander.  Setting the bit at position n inverts
- *               the polarity of that IO line, while clearing it results
- *               in normal polarity. For chips with fewer than 16 IO pins,
- *               high-end bits are ignored.
- * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
- *               is connected, via which it reports interrupt events
- *               across all GPIO lines.  This must be a real,
- *               pre-existing IRQ line.
- *               Setting this value < 0 disables the irq_chip functionality
- *               of the driver.
- * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
- *            IRQ lines will appear.  Similarly to gpio_base, the expander
- *            will create a block of irqs beginning at this number.
- *            This value is ignored if irq_summary is < 0.
- * @reset_during_probe: If set to true, the driver will trigger a full
- *                      reset of the chip at the beginning of the probe
- *                      in order to place it in a known state.

- * This tells the device controller to perform the specified request through

- * routine is called to return the request to the driver.  Any endpoint

- * request queued; they complete in FIFO order.  Once a gadget driver
- * submits a request, that request may not be examined or modified until it
- * is given back to that driver through the completion callback.
- *
- * Each request is turned into one or more packets.  The controller driver
- * never merges adjacent requests into the same packet.  OUT transfers
- * will sometimes use data that's already buffered in the hardware.
- * Drivers can rely on the fact that the first byte of the request's buffer
- * always corresponds to the first byte of some USB packet, for both
- * IN and OUT transfers.
- *
- * Bulk endpoints can queue any amount of data; the transfer is packetized
- * automatically.  The last packet will be short if the request doesn't fill it
- * out completely.  Zero length packets (ZLPs) should be avoided in portable
- * protocols since not all usb hardware can successfully handle zero length
- * packets.  (ZLPs may be explicitly written, and may be implicitly written if
- * the request 'zero' flag is set.)  Bulk endpoints may also be used
- * for interrupt transfers; but the reverse is not true, and some endpoints
- * won't support every interrupt transfer.  (Such as 768 byte packets.)
- *
- * Interrupt-only endpoints are less functional than bulk endpoints, for
- * example by not supporting queueing or not handling buffers that are
- * larger than the endpoint's maxpacket size.  They may also treat data
- * toggle differently.
- *
- * Control endpoints ... after getting a setup() callback, the driver queues
- * one response (even if it would be zero length).  That enables the
- * status ack, after transferring data as specified in the response.  Setup
- * functions may return negative error codes to generate protocol stalls.
- * (Note that some USB device controllers disallow protocol stall responses
- * in some cases.)  When control responses are deferred (the response is
- * written after the setup callback returns), then usb_ep_set_halt() may be
- * used on ep0 to trigger protocol stalls.  Depending on the controller,
- * it may not be possible to trigger a status-stage protocol stall when the
- * data stage is over, that is, from within the response's completion
- * routine.
- *
- * For periodic endpoints, like interrupt or isochronous ones, the usb host
- * arranges to poll once per interval, and the gadget driver usually will
- * have queued some data to transfer at that time.
