1024 tristate "Parallel port adapter"
1029 This supports parallel port I2C adapters such as the ones made by
1030 Philips or Velleman, Analog Devices evaluation boards, and more.
1031 Basically any adapter using the parallel port as an I2C bus with
1032 no extra chipset is supported by this driver, or could be.
1034 This driver is a replacement for (and was inspired by) an older
1035 driver named i2c-philips-par. The new driver supports more devices,
1036 and makes it easier to add support for new devices.
1038 An adapter type parameter is now mandatory. Please read the file
1039 Documentation/i2c/busses/i2c-parport for details.
1041 Another driver exists, named i2c-parport-light, which doesn't depend
1042 on the parport driver. This is meant for embedded systems. Don't say
1043 Y here if you intend to say Y or M there.
1045 This support is also available as a module. If so, the module
1046 will be called i2c-parport.
1048 config I2C_PARPORT_LIGHT
1049 tristate "Parallel port adapter (light)"
1053 This supports parallel port I2C adapters such as the ones made by
1054 Philips or Velleman, Analog Devices evaluation boards, and more.
1055 Basically any adapter using the parallel port as an I2C bus with
1056 no extra chipset is supported by this driver, or could be.
1058 This driver is a light version of i2c-parport. It doesn't depend
1059 on the parport driver, and uses direct I/O access instead. This
1060 might be preferred on embedded systems where wasting memory for
1061 the clean but heavy parport handling is not an option. The
1062 drawback is a reduced portability and the impossibility to
1063 daisy-chain other parallel port devices.
1065 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1066 both is possible but both modules should not be loaded at the same
1069 This support is also available as a module. If so, the module
1070 will be called i2c-parport-light.

1091 of the input-utils package.
1095 This support is also available as a module. If so, the module
1096 will be called i2c-taos-evm.

1148 This driver supports ISA boards using the Philips PCA9564/PCA9665
1149 parallel bus to I2C bus controller.
1151 This driver can also be built as a module. If so, the module
1152 will be called i2c-pca-isa.
1154 This device is almost undetectable and using this driver on a
1155 system which doesn't have this device will result in long
1156 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1157 time). If unsure, say N.
