34 * struct cec_msg - CEC message structure.
35 * @ts: Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
36 * driver. It is set when the message transmission has finished
37 * and it is set when a message was received.
38 * @len: Length in bytes of the message.
39 * @timeout: The timeout (in ms) that is used to timeout CEC_RECEIVE.
40 * Set to 0 if you want to wait forever. This timeout can also be
41 * used with CEC_TRANSMIT as the timeout for waiting for a reply.
42 * If 0, then it will use a 1 second timeout instead of waiting
43 * forever as is done with CEC_RECEIVE.
44 * @sequence: The framework assigns a sequence number to messages that are
45 * sent. This can be used to track replies to previously sent
48 * @rx_status: The message receive status bits. Set by the driver.
49 * @tx_status: The message transmit status bits. Set by the driver.

52 * CEC_TRANSMIT. If non-zero, then wait for a reply with this
53 * opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
54 * a possible ABORT reply. If there was an error when sending the
55 * msg or FeatureAbort was returned, then reply is set to 0.
56 * If reply is non-zero upon return, then len/msg are set to
57 * the received message.
58 * If reply is zero upon return and status has the
59 * CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
60 * the received feature abort message.

62 * CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
63 * all. If reply is non-zero for CEC_TRANSMIT and the message is a
64 * broadcast, then -EINVAL is returned.
