298 depends on I2C && PARPORT
301 This supports parallel port I2C adapters such as the ones made by
302 Philips or Velleman, Analog Devices evaluation boards, and more.
303 Basically any adapter using the parallel port as an I2C bus with
304 no extra chipset is supported by this driver, or could be.
306 This driver is a replacement for (and was inspired by) an older
307 driver named i2c-philips-par. The new driver supports more devices,
308 and makes it easier to add support for new devices.
310 An adapter type parameter is now mandatory. Please read the file
311 Documentation/i2c/busses/i2c-parport for details.

330 This driver is a light version of i2c-parport. It doesn't depend
331 on the parport driver, and uses direct I/O access instead. This
332 might be preferred on embedded systems where wasting memory for
333 the clean but heavy parport handling is not an option. The
334 drawback is a reduced portability and the impossibility to
335 daisy-chain other parallel port devices.
337 Don't say Y here if you said Y or M to i2c-parport. Saying M to
338 both is possible but both modules should not be loaded at the same
