983 tristate "Parallel port adapter"
988 This supports parallel port I2C adapters such as the ones made by
989 Philips or Velleman, Analog Devices evaluation boards, and more.
990 Basically any adapter using the parallel port as an I2C bus with
991 no extra chipset is supported by this driver, or could be.
993 This driver is a replacement for (and was inspired by) an older
994 driver named i2c-philips-par. The new driver supports more devices,
995 and makes it easier to add support for new devices.
997 An adapter type parameter is now mandatory. Please read the file
998 Documentation/i2c/busses/i2c-parport for details.
1000 Another driver exists, named i2c-parport-light, which doesn't depend
1001 on the parport driver. This is meant for embedded systems. Don't say
1002 Y here if you intend to say Y or M there.
1004 This support is also available as a module. If so, the module
1005 will be called i2c-parport.

1008 tristate "Parallel port adapter (light)"
1012 This supports parallel port I2C adapters such as the ones made by
1013 Philips or Velleman, Analog Devices evaluation boards, and more.
1014 Basically any adapter using the parallel port as an I2C bus with
1015 no extra chipset is supported by this driver, or could be.
1017 This driver is a light version of i2c-parport. It doesn't depend
1018 on the parport driver, and uses direct I/O access instead. This
1019 might be preferred on embedded systems where wasting memory for
1020 the clean but heavy parport handling is not an option. The
1021 drawback is a reduced portability and the impossibility to
1022 daisy-chain other parallel port devices.
1024 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1025 both is possible but both modules should not be loaded at the same
1028 This support is also available as a module. If so, the module
1029 will be called i2c-parport-light.

1110 This driver can also be built as a module. If so, the module
1111 will be called i2c-pca-isa.
1113 This device is almost undetectable and using this driver on a
1114 system which doesn't have this device will result in long
1115 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1116 time). If unsure, say N.
