David Brownell24d0fb422007-10-13 23:56:32 +0200298 This driver is BROKEN because the controller which it uses
299 will easily trigger RX overrun and TX underrun errors. Using
300 low I2C clock rates may partially work around those issues
301 on some systems. Another serious problem is that there is no
302 documented way to issue repeated START conditions, as needed
303 to support combined I2C messages. Use the i2c-gpio driver
304 unless your system can cope with those limitations.

383 This driver can access PCH I2C bus device.
384
385 This driver also can be used for LAPIS Semiconductor IOH(Input/
386 Output Hub), ML7213, ML7223 and ML7831.
387 ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is
388 for MP(Media Phone) use and ML7831 IOH is for general purpose use.
389 ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series.
390 ML7213/ML7223/ML7831 is completely compatible for Intel EG20T PCH.

730 This supports parallel port I2C adapters such as the ones made by
731 Philips or Velleman, Analog Devices evaluation boards, and more.
732 Basically any adapter using the parallel port as an I2C bus with
733 no extra chipset is supported by this driver, or could be.
734
735 This driver is a replacement for (and was inspired by) an older
736 driver named i2c-philips-par. The new driver supports more devices,
737 and makes it easier to add support for new devices.
Mark M. Hoffmane97b81d2006-03-23 16:50:25 +0100738
739 An adapter type parameter is now mandatory. Please read the file

759 This driver is a light version of i2c-parport. It doesn't depend
760 on the parport driver, and uses direct I/O access instead. This
Matt LaPlante09509602006-10-03 22:31:37 +0200761 might be preferred on embedded systems where wasting memory for
Linus Torvalds1da177e2005-04-16 15:20:36 -0700762 the clean but heavy parport handling is not an option. The
763 drawback is a reduced portability and the impossibility to
