760 This supports parallel port I2C adapters such as the ones made by
761 Philips or Velleman, Analog Devices evaluation boards, and more.
762 Basically any adapter using the parallel port as an I2C bus with
763 no extra chipset is supported by this driver, or could be.
764
765 This driver is a replacement for (and was inspired by) an older
766 driver named i2c-philips-par. The new driver supports more devices,
767 and makes it easier to add support for new devices.
Mark M. Hoffmane97b81d2006-03-23 16:50:25 +0100768

789 This driver is a light version of i2c-parport. It doesn't depend

Matt LaPlante09509602006-10-03 22:31:37 +0200791 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700792 the clean but heavy parport handling is not an option. The
793 drawback is a reduced portability and the impossibility to
