David Brownell24d0fb42007-10-13 23:56:32 +0200300 This driver is BROKEN because the controller which it uses
301 will easily trigger RX overrun and TX underrun errors. Using
302 low I2C clock rates may partially work around those issues
303 on some systems. Another serious problem is that there is no
304 documented way to issue repeated START conditions, as needed
305 to support combined I2C messages. Use the i2c-gpio driver
306 unless your system can cope with those limitations.

737 This supports parallel port I2C adapters such as the ones made by
738 Philips or Velleman, Analog Devices evaluation boards, and more.
739 Basically any adapter using the parallel port as an I2C bus with
740 no extra chipset is supported by this driver, or could be.
741
742 This driver is a replacement for (and was inspired by) an older
743 driver named i2c-philips-par. The new driver supports more devices,
744 and makes it easier to add support for new devices.
Mark M. Hoffmane97b81d2006-03-23 16:50:25 +0100745
