| + * 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. |
