- * I2C Message - used for pure i2c transaction, also from /dev interface
+/**
+ * struct i2c_msg - an I2C transaction segment beginning with START
+ * @addr: Slave address, either seven or ten bits.  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).
