This driver is BROKEN because the controller which it uses will easily trigger RX overrun and TX underrun errors. Using low I2C clock rates may partially work around those issues on some systems. Another serious problem is that there is no documented way to issue repeated START conditions, as needed to support combined I2C messages. Use the i2c-gpio driver unless your system can cope with those limitations. config I2C_AU1550 tristate "Au1550/Au1200 SMBus interface" depends on SOC_AU1550 || SOC_AU1200 help If you say yes to this option, support will be included for the Au1550 and Au1200 SMBus interface.

Basically any adapter using the parallel port as an I2C bus with no extra chipset is supported by this driver, or could be. This driver is a replacement for (and was inspired by) an older driver named i2c-philips-par. The new driver supports more devices, and makes it easier to add support for new devices. An adapter type parameter is now mandatory. Please read the file Documentation/i2c/busses/i2c-parport for details. Another driver exists, named i2c-parport-light, which doesn't depend on the parport driver. This is meant for embedded systems. Don't say Y here if you intend to say Y or M there.

Basically any adapter using the parallel port as an I2C bus with no extra chipset is supported by this driver, or could be. This driver is a light version of i2c-parport. It doesn't depend on the parport driver, and uses direct I/O access instead. This might be preferred on embedded systems where wasting memory for the clean but heavy parport handling is not an option. The drawback is a reduced portability and the impossibility to daisy-chain other parallel port devices. Don't say Y here if you said Y or M to i2c-parport.
