556	  This supports parallel port I2C adapters such as the ones made by
557	  Philips or Velleman, Analog Devices evaluation boards, and more.
558	  Basically any adapter using the parallel port as an I2C bus with
559	  no extra chipset is supported by this driver, or could be.
560
561	  This driver is a replacement for (and was inspired by) an older
562	  driver named i2c-philips-par.  The new driver supports more devices,
563	  and makes it easier to add support for new devices.
564
565	  An adapter type parameter is now mandatory.  Please read the file
566	  Documentation/i2c/busses/i2c-parport for details.

570	  Y here if you intend to say Y or M there.

583
584	  This driver is a light version of i2c-parport.  It doesn't depend
585	  on the parport driver, and uses direct I/O access instead.  This
586	  might be preferred on embedded systems where wasting memory for
587	  the clean but heavy parport handling is not an option.  The
588	  drawback is a reduced portability and the impossibility to
589	  daisy-chain other parallel port devices.
590
591	  Don't say Y here if you said Y or M to i2c-parport.  Saying M to
592	  both is possible but both modules should not be loaded at the same
