47 * @tx_ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
48 * driver when the message transmission has finished.
49 * @rx_ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
50 * driver when the message was received.
51 * @len: Length in bytes of the message.
52 * @timeout: The timeout (in ms) that is used to timeout CEC_RECEIVE.
53 * Set to 0 if you want to wait forever. This timeout can also be
54 * used with CEC_TRANSMIT as the timeout for waiting for a reply.
55 * If 0, then it will use a 1 second timeout instead of waiting
56 * forever as is done with CEC_RECEIVE.
57 * @sequence: The framework assigns a sequence number to messages that are
58 * sent. This can be used to track replies to previously sent
61 * @msg: The message payload.
62 * @reply: This field is ignored with CEC_RECEIVE and is only used by
63 * CEC_TRANSMIT. If non-zero, then wait for a reply with this
64 * opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
65 * a possible ABORT reply. If there was an error when sending the
66 * msg or FeatureAbort was returned, then reply is set to 0.
67 * If reply is non-zero upon return, then len/msg are set to
68 * the received message.
69 * If reply is zero upon return and status has the
70 * CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
71 * the received feature abort message.
72 * If reply is zero upon return and status has the
73 * CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
74 * all. If reply is non-zero for CEC_TRANSMIT and the message is a
75 * broadcast, then -EINVAL is returned.
76 * if reply is non-zero, then timeout is set to 1000 (the required
77 * maximum response time).
78 * @rx_status: The message receive status bits. Set by the driver.
79 * @tx_status: The message transmit status bits. Set by the driver.
