This supports the use of the I2C interface in the Apple Hydra Mac
I/O chip on some CHRP machines (e.g. the LongTrail). Say Y if you
have such a machine.
This support is also available as a module. If so, the module
will be called i2c-hydra.

help
This exposes the various PowerMac i2c interfaces to the linux i2c
layer and to userland. It is used by various drivers on the PowerMac
platform, and should generally be enabled.
This support is also available as a module. If so, the module
will be called i2c-powermac.

config I2C_AT91
tristate "Atmel AT91 I2C Two-Wire interface (TWI)"
depends on ARCH_AT91 && EXPERIMENTAL && BROKEN
help
This supports the use of the I2C interface on Atmel AT91
processors.
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.

help
This supports parallel port I2C adapters such as the ones made by
Philips or Velleman, Analog Devices evaluation boards, and more.
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.
This support is also available as a module. If so, the module
will be called i2c-parport.

This supports parallel port I2C adapters such as the ones made by
Philips or Velleman, Analog Devices evaluation boards, and more.
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. Saying M to
both is possible but both modules should not be loaded at the same
time.
This support is also available as a module. If so, the module
will be called i2c-parport-light.
