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

652 tristate "Parallel port adapter"
657 This supports parallel port I2C adapters such as the ones made by
658 Philips or Velleman, Analog Devices evaluation boards, and more.
659 Basically any adapter using the parallel port as an I2C bus with
660 no extra chipset is supported by this driver, or could be.
662 This driver is a replacement for (and was inspired by) an older
663 driver named i2c-philips-par. The new driver supports more devices,
664 and makes it easier to add support for new devices.
666 An adapter type parameter is now mandatory. Please read the file
667 Documentation/i2c/busses/i2c-parport for details.
669 Another driver exists, named i2c-parport-light, which doesn't depend
670 on the parport driver. This is meant for embedded systems. Don't say

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