568 This driver is for PCH(Platform controller Hub) I2C of EG20T which
569 is an IOH(Input/Output Hub) for x86 embedded processor.
570 This driver can access PCH I2C bus device.
571
572 This driver also can be used for LAPIS Semiconductor IOH(Input/
573 Output Hub), ML7213, ML7223 and ML7831.
574 ML7213 IOH is for IVI(In-Vehicle Infotainment) use, ML7223 IOH is
575 for MP(Media Phone) use and ML7831 IOH is for general purpose use.
576 ML7213/ML7223/ML7831 is companion chip for Intel Atom E6xx series.

1142 This supports parallel port I2C adapters such as the ones made by
1143 Philips or Velleman, Analog Devices evaluation boards, and more.
1144 Basically any adapter using the parallel port as an I2C bus with
1145 no extra chipset is supported by this driver, or could be.
1146
1147 This driver is a replacement for (and was inspired by) an older
1148 driver named i2c-philips-par. The new driver supports more devices,
1149 and makes it easier to add support for new devices.
1150
1151 An adapter type parameter is now mandatory. Please read the file
1152 Documentation/i2c/busses/i2c-parport for details.

1171 This driver is a light version of i2c-parport. It doesn't depend
1172 on the parport driver, and uses direct I/O access instead. This
1173 might be preferred on embedded systems where wasting memory for
1174 the clean but heavy parport handling is not an option. The
1175 drawback is a reduced portability and the impossibility to
1176 daisy-chain other parallel port devices.
