/**
|
||||
* 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).
