help
This supports the use of the I2C interface on Atmel AT91

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.

This supports parallel port I2C adapters such as the ones made by

This driver is a replacement for (and was inspired by) an older

An adapter type parameter is now mandatory. Please read the file
Documentation/i2c/busses/i2c-parport for details.

Basically any adapter using the parallel port as an I2C bus with

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. Saying M to
