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

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

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