struct cec_msg - CEC message structure. @tx_ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. 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. Set by the driver.
