735 no extra chipset is supported by this driver, or could be.

737 This driver is a light version of i2c-parport. It doesn't depend
738 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200739 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700740 the clean but heavy parport handling is not an option. The
741 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +0200742 daisy-chain other parallel port devices.
