1150 tristate "Parallel port adapter"
1155 This supports parallel port I2C adapters such as the ones made by
1156 Philips or Velleman, Analog Devices evaluation boards, and more.
1157 Basically any adapter using the parallel port as an I2C bus with
1158 no extra chipset is supported by this driver, or could be.
1160 This driver is a replacement for (and was inspired by) an older
1161 driver named i2c-philips-par. The new driver supports more devices,
1162 and makes it easier to add support for new devices.
1164 An adapter type parameter is now mandatory. Please read the file
1165 Documentation/i2c/busses/i2c-parport for details.
1167 Another driver exists, named i2c-parport-light, which doesn't depend
1168 on the parport driver. This is meant for embedded systems. Don't say
1169 Y here if you intend to say Y or M there.

1181 Basically any adapter using the parallel port as an I2C bus with
1182 no extra chipset is supported by this driver, or could be.
1184 This driver is a light version of i2c-parport. It doesn't depend
1185 on the parport driver, and uses direct I/O access instead. This
1186 might be preferred on embedded systems where wasting memory for
1187 the clean but heavy parport handling is not an option. The
1188 drawback is a reduced portability and the impossibility to
1189 daisy-chain other parallel port devices.
1191 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1192 both is possible but both modules should not be loaded at the same

1289 will be called i2c-pca-isa.
1291 This device is almost undetectable and using this driver on a
1292 system which doesn't have this device will result in long
