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.
