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

741 This supports parallel port I2C adapters such as the ones made by
742 Philips or Velleman, Analog Devices evaluation boards, and more.
743 Basically any adapter using the parallel port as an I2C bus with
744 no extra chipset is supported by this driver, or could be.
745
746 This driver is a light version of i2c-parport. It doesn't depend
747 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200748 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700749 the clean but heavy parport handling is not an option. The
750 drawback is a reduced portability and the impossibility to
Matt LaPlante09509602006-10-03 22:31:37 +0200751 daisy-chain other parallel port devices.
