David Brownell24d0fb42007-10-13 23:56:32 +0200293 This driver is BROKEN because the controller which it uses
294 will easily trigger RX overrun and TX underrun errors. Using
295 low I2C clock rates may partially work around those issues
296 on some systems. Another serious problem is that there is no

761 This supports parallel port I2C adapters such as the ones made by
762 Philips or Velleman, Analog Devices evaluation boards, and more.
763 Basically any adapter using the parallel port as an I2C bus with
764 no extra chipset is supported by this driver, or could be.
765
766 This driver is a light version of i2c-parport. It doesn't depend
767 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200768 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700769 the clean but heavy parport handling is not an option. The
770 drawback is a reduced portability and the impossibility to
