1140 tristate "Parallel port adapter"
1145 This supports parallel port I2C adapters such as the ones made by
1146 Philips or Velleman, Analog Devices evaluation boards, and more.
1147 Basically any adapter using the parallel port as an I2C bus with
1148 no extra chipset is supported by this driver, or could be.
1150 This driver is a replacement for (and was inspired by) an older
1151 driver named i2c-philips-par. The new driver supports more devices,
1152 and makes it easier to add support for new devices.
1154 An adapter type parameter is now mandatory. Please read the file
1155 Documentation/i2c/busses/i2c-parport for details.
1157 Another driver exists, named i2c-parport-light, which doesn't depend
1158 on the parport driver. This is meant for embedded systems. Don't say
1159 Y here if you intend to say Y or M there.

1171 Basically any adapter using the parallel port as an I2C bus with
1172 no extra chipset is supported by this driver, or could be.
1174 This driver is a light version of i2c-parport. It doesn't depend
1175 on the parport driver, and uses direct I/O access instead. This
1176 might be preferred on embedded systems where wasting memory for
1177 the clean but heavy parport handling is not an option. The
1178 drawback is a reduced portability and the impossibility to
1179 daisy-chain other parallel port devices.
1181 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1182 both is possible but both modules should not be loaded at the same
