742 This supports parallel port I2C adapters such as the ones made by
743 Philips or Velleman, Analog Devices evaluation boards, and more.
744 Basically any adapter using the parallel port as an I2C bus with
745 no extra chipset is supported by this driver, or could be.
746
747 This driver is a light version of i2c-parport. It doesn't depend
748 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200749 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700750 the clean but heavy parport handling is not an option. The
751 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +0200752 daisy-chain other parallel port devices.
