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

552 tristate "Parallel port adapter"
556 This supports parallel port I2C adapters such as the ones made by
557 Philips or Velleman, Analog Devices evaluation boards, and more.
558 Basically any adapter using the parallel port as an I2C bus with
559 no extra chipset is supported by this driver, or could be.
561 This driver is a replacement for (and was inspired by) an older
562 driver named i2c-philips-par. The new driver supports more devices,
563 and makes it easier to add support for new devices.
565 An adapter type parameter is now mandatory. Please read the file
566 Documentation/i2c/busses/i2c-parport for details.
568 Another driver exists, named i2c-parport-light, which doesn't depend
569 on the parport driver. This is meant for embedded systems. Don't say
570 Y here if you intend to say Y or M there.

581 Basically any adapter using the parallel port as an I2C bus with
582 no extra chipset is supported by this driver, or could be.
584 This driver is a light version of i2c-parport. It doesn't depend
585 on the parport driver, and uses direct I/O access instead. This
586 might be preferred on embedded systems where wasting memory for
587 the clean but heavy parport handling is not an option. The
588 drawback is a reduced portability and the impossibility to
589 daisy-chain other parallel port devices.
591 Don't say Y here if you said Y or M to i2c-parport. Saying M to
592 both is possible but both modules should not be loaded at the same
