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