17  * struct cec_msg - CEC message structure.
18  * @tx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
19  *		driver when the message transmission has finished.
20  * @rx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
21  *		driver when the message was received.
22  * @len:	Length in bytes of the message.
23  * @timeout:	The timeout (in ms) that is used to timeout CEC_RECEIVE.
24  *		Set to 0 if you want to wait forever. This timeout can also be
25  *		used with CEC_TRANSMIT as the timeout for waiting for a reply.
26  *		If 0, then it will use a 1 second timeout instead of waiting
27  *		forever as is done with CEC_RECEIVE.
28  * @sequence:	The framework assigns a sequence number to messages that are
29  *		sent. This can be used to track replies to previously sent
30  *		messages.
31  * @flags:	Set to 0.
32  * @msg:	The message payload.
33  * @reply:	This field is ignored with CEC_RECEIVE and is only used by
34  *		CEC_TRANSMIT. If non-zero, then wait for a reply with this
35  *		opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
36  *		a possible ABORT reply. If there was an error when sending the
37  *		msg or FeatureAbort was returned, then reply is set to 0.
38  *		If reply is non-zero upon return, then len/msg are set to
39  *		the received message.
40  *		If reply is zero upon return and status has the
41  *		CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
42  *		the received feature abort message.
43  *		If reply is zero upon return and status has the
44  *		CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
45  *		all. If reply is non-zero for CEC_TRANSMIT and the message is a
46  *		broadcast, then -EINVAL is returned.
47  *		if reply is non-zero, then timeout is set to 1000 (the required
48  *		maximum response time).
49  * @rx_status:	The message receive status bits. Set by the driver.
50  * @tx_status:	The message transmit status bits. Set by the driver.
51  * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
52  * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
53  * @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
54  *		driver.
55  * @tx_error_cnt: The number of 'Error' events. Set by the driver.

474  * The remainder of this header defines all CEC messages and operands.
475  * The format matters since it the cec-ctl utility parses it to generate
476  * code for implementing all these messages.
477  *
478  * Comments ending with 'Feature' group messages for each feature.
479  * If messages are part of multiple features, then the "Has also"
480  * comment is used to list the previously defined messages that are
481  * supported by the feature.
482  *
483  * Before operands are defined a comment is added that gives the
484  * name of the operand and in brackets the variable name of the
485  * corresponding argument in the cec-funcs.h function.
