1019 tristate "Parallel port adapter"
1024 This supports parallel port I2C adapters such as the ones made by
1025 Philips or Velleman, Analog Devices evaluation boards, and more.
1026 Basically any adapter using the parallel port as an I2C bus with
1027 no extra chipset is supported by this driver, or could be.
1029 This driver is a replacement for (and was inspired by) an older
1030 driver named i2c-philips-par. The new driver supports more devices,
1031 and makes it easier to add support for new devices.
1033 An adapter type parameter is now mandatory. Please read the file
1034 Documentation/i2c/busses/i2c-parport for details.
1036 Another driver exists, named i2c-parport-light, which doesn't depend
1037 on the parport driver. This is meant for embedded systems. Don't say
1038 Y here if you intend to say Y or M there.
1040 This support is also available as a module. If so, the module
1041 will be called i2c-parport.
1043 config I2C_PARPORT_LIGHT
1044 tristate "Parallel port adapter (light)"
1048 This supports parallel port I2C adapters such as the ones made by
1049 Philips or Velleman, Analog Devices evaluation boards, and more.
1050 Basically any adapter using the parallel port as an I2C bus with
1051 no extra chipset is supported by this driver, or could be.
1053 This driver is a light version of i2c-parport. It doesn't depend
1054 on the parport driver, and uses direct I/O access instead. This
1055 might be preferred on embedded systems where wasting memory for
1056 the clean but heavy parport handling is not an option. The
1057 drawback is a reduced portability and the impossibility to
1058 daisy-chain other parallel port devices.
1060 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1061 both is possible but both modules should not be loaded at the same
1064 This support is also available as a module. If so, the module
1065 will be called i2c-parport-light.

1086 of the input-utils package.
1090 This support is also available as a module. If so, the module
1091 will be called i2c-taos-evm.

1143 This driver supports ISA boards using the Philips PCA9564/PCA9665
1144 parallel bus to I2C bus controller.
1146 This driver can also be built as a module. If so, the module
1147 will be called i2c-pca-isa.
1149 This device is almost undetectable and using this driver on a
1150 system which doesn't have this device will result in long
1151 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1152 time). If unsure, say N.
