85 low I2C clock rates may partially work around those issues
86 on some systems. Another serious problem is that there is no
87 documented way to issue repeated START conditions, as needed
88 to support combined I2C messages. Use the i2c-gpio driver
89 unless your system can cope with those limitations.

358 Philips or Velleman, Analog Devices evaluation boards, and more.
359 Basically any adapter using the parallel port as an I2C bus with
360 no extra chipset is supported by this driver, or could be.
362 This driver is a replacement for (and was inspired by) an older
363 driver named i2c-philips-par. The new driver supports more devices,
364 and makes it easier to add support for new devices.
366 An adapter type parameter is now mandatory. Please read the file
367 Documentation/i2c/busses/i2c-parport for details.

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