+ * 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.
