  51. * @len: Length in bytes of the message.

  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
  59. * messages.
  60. * @flags: Set to 0.
  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.

  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.
  80. * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
