1106 tristate "Parallel port adapter"
1111 This supports parallel port I2C adapters such as the ones made by
1112 Philips or Velleman, Analog Devices evaluation boards, and more.
1113 Basically any adapter using the parallel port as an I2C bus with
1114 no extra chipset is supported by this driver, or could be.
1116 This driver is a replacement for (and was inspired by) an older
1117 driver named i2c-philips-par. The new driver supports more devices,
1118 and makes it easier to add support for new devices.
1120 An adapter type parameter is now mandatory. Please read the file
1121 Documentation/i2c/busses/i2c-parport for details.
1123 Another driver exists, named i2c-parport-light, which doesn't depend
1124 on the parport driver. This is meant for embedded systems. Don't say
1125 Y here if you intend to say Y or M there.

1137 Basically any adapter using the parallel port as an I2C bus with
1138 no extra chipset is supported by this driver, or could be.
1140 This driver is a light version of i2c-parport. It doesn't depend
1141 on the parport driver, and uses direct I/O access instead. This
1142 might be preferred on embedded systems where wasting memory for
1143 the clean but heavy parport handling is not an option. The
1144 drawback is a reduced portability and the impossibility to
1145 daisy-chain other parallel port devices.
1147 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1148 both is possible but both modules should not be loaded at the same
