957 DLN2, a USB to I2C interface.
959 This driver can also be built as a module. If so, the module
960 will be called i2c-dln2.
963 tristate "Parallel port adapter"
968 This supports parallel port I2C adapters such as the ones made by
969 Philips or Velleman, Analog Devices evaluation boards, and more.
970 Basically any adapter using the parallel port as an I2C bus with
971 no extra chipset is supported by this driver, or could be.
973 This driver is a replacement for (and was inspired by) an older
974 driver named i2c-philips-par. The new driver supports more devices,
975 and makes it easier to add support for new devices.
977 An adapter type parameter is now mandatory. Please read the file
978 Documentation/i2c/busses/i2c-parport for details.
980 Another driver exists, named i2c-parport-light, which doesn't depend
981 on the parport driver. This is meant for embedded systems. Don't say
982 Y here if you intend to say Y or M there.
984 This support is also available as a module. If so, the module
985 will be called i2c-parport.
987 config I2C_PARPORT_LIGHT
988 tristate "Parallel port adapter (light)"
992 This supports parallel port I2C adapters such as the ones made by
993 Philips or Velleman, Analog Devices evaluation boards, and more.
994 Basically any adapter using the parallel port as an I2C bus with
995 no extra chipset is supported by this driver, or could be.
997 This driver is a light version of i2c-parport. It doesn't depend
998 on the parport driver, and uses direct I/O access instead. This
999 might be preferred on embedded systems where wasting memory for
1000 the clean but heavy parport handling is not an option. The
1001 drawback is a reduced portability and the impossibility to
1002 daisy-chain other parallel port devices.
1004 Don't say Y here if you said Y or M to i2c-parport. Saying M to
1005 both is possible but both modules should not be loaded at the same
1008 This support is also available as a module. If so, the module
1009 will be called i2c-parport-light.

1087 This driver supports ISA boards using the Philips PCA9564/PCA9665
1088 parallel bus to I2C bus controller.
1090 This driver can also be built as a module. If so, the module
1091 will be called i2c-pca-isa.
1093 This device is almost undetectable and using this driver on a
1094 system which doesn't have this device will result in long
1095 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
1096 time). If unsure, say N.
