45 * struct cec_msg - CEC message structure.
46 * @tx_ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
47 * driver when the message transmission has finished.
48 * @rx_ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
49 * driver when the message was received.
50 * @len: Length in bytes of the message.
51 * @timeout: The timeout (in ms) that is used to timeout CEC_RECEIVE.
52 * Set to 0 if you want to wait forever. This timeout can also be
53 * used with CEC_TRANSMIT as the timeout for waiting for a reply.
54 * If 0, then it will use a 1 second timeout instead of waiting
55 * forever as is done with CEC_RECEIVE.
56 * @sequence: The framework assigns a sequence number to messages that are
57 * sent. This can be used to track replies to previously sent
60 * @msg: The message payload.
61 * @reply: This field is ignored with CEC_RECEIVE and is only used by
62 * CEC_TRANSMIT. If non-zero, then wait for a reply with this
63 * opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
64 * a possible ABORT reply. If there was an error when sending the
65 * msg or FeatureAbort was returned, then reply is set to 0.
66 * If reply is non-zero upon return, then len/msg are set to
67 * the received message.
68 * If reply is zero upon return and status has the
69 * CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
70 * the received feature abort message.
71 * If reply is zero upon return and status has the
72 * CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
73 * all. If reply is non-zero for CEC_TRANSMIT and the message is a
74 * broadcast, then -EINVAL is returned.
75 * if reply is non-zero, then timeout is set to 1000 (the required
76 * maximum response time).
77 * @rx_status: The message receive status bits. Set by the driver.
78 * @tx_status: The message transmit status bits. Set by the driver.
79 * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
80 * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
