Linus Torvalds1da177e2005-04-16 15:20:36 -0700746 Another driver exists, named i2c-parport-light, which doesn't depend
747 on the parport driver. This is meant for embedded systems. Don't say
748 Y here if you intend to say Y or M there.

758 This supports parallel port I2C adapters such as the ones made by
759 Philips or Velleman, Analog Devices evaluation boards, and more.
760 Basically any adapter using the parallel port as an I2C bus with
761 no extra chipset is supported by this driver, or could be.
762
763 This driver is a light version of i2c-parport. It doesn't depend
764 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200765 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700766 the clean but heavy parport handling is not an option. The
767 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +0200768 daisy-chain other parallel port devices.
