  17  * struct cec_msg - CEC message structure.
  18  * @tx_ts:      Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
  19  *              driver when the message transmission has finished.
  20  * @rx_ts:      Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
  21  *              driver when the message was received.
  22  * @len:        Length in bytes of the message.
  23  * @timeout:    The timeout (in ms) that is used to timeout CEC_RECEIVE.
  24  *              Set to 0 if you want to wait forever. This timeout can also be
  25  *              used with CEC_TRANSMIT as the timeout for waiting for a reply.
  26  *              If 0, then it will use a 1 second timeout instead of waiting
  27  *              forever as is done with CEC_RECEIVE.
  28  * @sequence:   The framework assigns a sequence number to messages that are
  29  *              sent. This can be used to track replies to previously sent
  30  *              messages.
  31  * @flags:      Set to 0.
  32  * @msg:        The message payload.
  33  * @reply:      This field is ignored with CEC_RECEIVE and is only used by
  34  *              CEC_TRANSMIT. If non-zero, then wait for a reply with this
  35  *              opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
  36  *              a possible ABORT reply. If there was an error when sending the
  37  *              msg or FeatureAbort was returned, then reply is set to 0.
  38  *              If reply is non-zero upon return, then len/msg are set to
  39  *              the received message.
  40  *              If reply is zero upon return and status has the
  41  *              CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
  42  *              the received feature abort message.
  43  *              If reply is zero upon return and status has the
  44  *              CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
  45  *              all. If reply is non-zero for CEC_TRANSMIT and the message is a
  46  *              broadcast, then -EINVAL is returned.
  47  *              if reply is non-zero, then timeout is set to 1000 (the required
  48  *              maximum response time).
  49  * @rx_status:  The message receive status bits. Set by the driver.
  50  * @tx_status:  The message transmit status bits. Set by the driver.
  51  * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
  52  * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
  53  * @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
  54  *              driver.
  55  * @tx_error_cnt: The number of 'Error' events. Set by the driver.
