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

626 tristate "Parallel port adapter"
631 This supports parallel port I2C adapters such as the ones made by
632 Philips or Velleman, Analog Devices evaluation boards, and more.
633 Basically any adapter using the parallel port as an I2C bus with
634 no extra chipset is supported by this driver, or could be.
636 This driver is a replacement for (and was inspired by) an older
637 driver named i2c-philips-par. The new driver supports more devices,
638 and makes it easier to add support for new devices.
640 An adapter type parameter is now mandatory. Please read the file
641 Documentation/i2c/busses/i2c-parport for details.
643 Another driver exists, named i2c-parport-light, which doesn't depend
644 on the parport driver. This is meant for embedded systems. Don't say
645 Y here if you intend to say Y or M there.

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

660 This driver is a light version of i2c-parport. It doesn't depend
661 on the parport driver, and uses direct I/O access instead. This
662 might be preferred on embedded systems where wasting memory for
663 the clean but heavy parport handling is not an option. The
664 drawback is a reduced portability and the impossibility to
665 daisy-chain other parallel port devices.
667 Don't say Y here if you said Y or M to i2c-parport. Saying M to
668 both is possible but both modules should not be loaded at the same
