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

505 comment "External I2C/SMBus adapter drivers"
508 tristate "Parallel port adapter"
512 This supports parallel port I2C adapters such as the ones made by
513 Philips or Velleman, Analog Devices evaluation boards, and more.
514 Basically any adapter using the parallel port as an I2C bus with
515 no extra chipset is supported by this driver, or could be.
517 This driver is a replacement for (and was inspired by) an older
518 driver named i2c-philips-par. The new driver supports more devices,
519 and makes it easier to add support for new devices.
521 An adapter type parameter is now mandatory. Please read the file
522 Documentation/i2c/busses/i2c-parport for details.
524 Another driver exists, named i2c-parport-light, which doesn't depend
525 on the parport driver. This is meant for embedded systems. Don't say
526 Y here if you intend to say Y or M there.

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