283 depends on ARCH_AT91 && EXPERIMENTAL && BROKEN
285 This supports the use of the I2C interface on Atmel AT91
288 This driver is BROKEN because the controller which it uses
289 will easily trigger RX overrun and TX underrun errors. Using
290 low I2C clock rates may partially work around those issues
291 on some systems. Another serious problem is that there is no
292 documented way to issue repeated START conditions, as needed
293 to support combined I2C messages. Use the i2c-gpio driver

581 tristate "Parallel port adapter"
586 This supports parallel port I2C adapters such as the ones made by
587 Philips or Velleman, Analog Devices evaluation boards, and more.
588 Basically any adapter using the parallel port as an I2C bus with
589 no extra chipset is supported by this driver, or could be.
591 This driver is a replacement for (and was inspired by) an older
592 driver named i2c-philips-par. The new driver supports more devices,
593 and makes it easier to add support for new devices.
595 An adapter type parameter is now mandatory. Please read the file
596 Documentation/i2c/busses/i2c-parport for details.
598 Another driver exists, named i2c-parport-light, which doesn't depend
599 on the parport driver. This is meant for embedded systems. Don't say
600 Y here if you intend to say Y or M there.

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

615 This driver is a light version of i2c-parport. It doesn't depend
616 on the parport driver, and uses direct I/O access instead. This
617 might be preferred on embedded systems where wasting memory for
618 the clean but heavy parport handling is not an option. The
619 drawback is a reduced portability and the impossibility to
620 daisy-chain other parallel port devices.
622 Don't say Y here if you said Y or M to i2c-parport. Saying M to
