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

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

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