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.
