1142 tristate "Parallel port adapter"
1147 This supports parallel port I2C adapters such as the ones made by
1148 Philips or Velleman, Analog Devices evaluation boards, and more.
1149 Basically any adapter using the parallel port as an I2C bus with
1150 no extra chipset is supported by this driver, or could be.
1152 This driver is a replacement for (and was inspired by) an older
1153 driver named i2c-philips-par. The new driver supports more devices,
1154 and makes it easier to add support for new devices.
1156 An adapter type parameter is now mandatory. Please read the file
1157 Documentation/i2c/busses/i2c-parport for details.
1159 Another driver exists, named i2c-parport-light, which doesn't depend
1160 on the parport driver. This is meant for embedded systems. Don't say
1161 Y here if you intend to say Y or M there.
1163 This support is also available as a module. If so, the module

1173 Basically any adapter using the parallel port as an I2C bus with
1174 no extra chipset is supported by this driver, or could be.
1176 This driver is a light version of i2c-parport. It doesn't depend
1177 on the parport driver, and uses direct I/O access instead. This
1178 might be preferred on embedded systems where wasting memory for
1179 the clean but heavy parport handling is not an option. The
1180 drawback is a reduced portability and the impossibility to
1181 daisy-chain other parallel port devices.
1183 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1184 both is possible but both modules should not be loaded at the same
