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

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