1131 tristate "Parallel port adapter"
1136 This supports parallel port I2C adapters such as the ones made by
1137 Philips or Velleman, Analog Devices evaluation boards, and more.
1138 Basically any adapter using the parallel port as an I2C bus with
1139 no extra chipset is supported by this driver, or could be.
1141 This driver is a replacement for (and was inspired by) an older
1142 driver named i2c-philips-par. The new driver supports more devices,
1143 and makes it easier to add support for new devices.
1145 An adapter type parameter is now mandatory. Please read the file
1146 Documentation/i2c/busses/i2c-parport for details.
1148 Another driver exists, named i2c-parport-light, which doesn't depend
1149 on the parport driver. This is meant for embedded systems. Don't say
1150 Y here if you intend to say Y or M there.

1162 Basically any adapter using the parallel port as an I2C bus with
1163 no extra chipset is supported by this driver, or could be.
1165 This driver is a light version of i2c-parport. It doesn't depend
1166 on the parport driver, and uses direct I/O access instead. This
1167 might be preferred on embedded systems where wasting memory for
1168 the clean but heavy parport handling is not an option. The
1169 drawback is a reduced portability and the impossibility to
1170 daisy-chain other parallel port devices.
1172 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1173 both is possible but both modules should not be loaded at the same
