When this is a ten ++ * bit address, I2C_M_TEN must be set in @flags and the adapter ++ * must support I2C_FUNC_10BIT_ADDR. ++ * @flags: I2C_M_RD is handled by all adapters. No other flags may be ++ * provided unless the adapter exported the relevant I2C_FUNC_* ++ * flags through i2c_check_functionality(). ++ * @len: Number of data bytes in @buf being read from or written to the ++ * I2C slave address. For read transactions where I2C_M_RECV_LEN ++ * is set, the caller guarantees that this buffer can hold up to ++ * 32 bytes in addition to the initial length byte sent by the ++ * slave (plus, if used, the SMBus PEC); and this value will be ++ * incremented by the number of block data bytes received. ++ * @buf: The buffer into which data is read, or from which it's written. ++ * ++ * An i2c_msg is the low level representation of one segment of an I2C ++ * transaction. It is visible to drivers in the @i2c_transfer() procedure, ++ * to userspace from i2c-dev, and to I2C adapter drivers through the ++ * @i2c_adapter.@master_xfer() method. ++ * ++ * Except when I2C "protocol mangling" is used, all I2C adapters implement ++ * the standard rules for I2C transactions. Each transaction begins with a ++ * START. That is followed by the slave address, and a bit encoding read ++ * versus write. Then follow all the data bytes, possibly including a byte ++ * with SMBus PEC. The transfer terminates with a NAK, or when all those ++ * bytes have been transferred and ACKed. If this is the last message in a ++ * group, it is followed by a STOP. Otherwise it is followed by the next ++ * @i2c_msg transaction segment, beginning with a (repeated) START. ++ * ++ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then ++ * passing certain @flags may have changed those standard protocol behaviors. ++ * Those flags are only for use with broken/nonconforming slaves, and with ++ * adapters which are known to support the specific mangling options they ++ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR). ++ */ ++struct i2c_msg { ++ __u16 addr;
