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

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