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

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