1017	  Another driver exists, named i2c-parport-light, which doesn't depend
1018	  on the parport driver.  This is meant for embedded systems. Don't say
1019	  Y here if you intend to say Y or M there.
1020
1021	  This support is also available as a module.  If so, the module
1022	  will be called i2c-parport.

1028	help
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.
1033
1034	  This driver is a light version of i2c-parport.  It doesn't depend
1035	  on the parport driver, and uses direct I/O access instead.  This
1036	  might be preferred on embedded systems where wasting memory for
1037	  the clean but heavy parport handling is not an option.  The
1038	  drawback is a reduced portability and the impossibility to
1039	  daisy-chain other parallel port devices.
1040
1041	  Don't say Y here if you said Y or M to i2c-parport.  Saying M to
1042	  both is possible but both modules should not be loaded at the same
1043	  time.
1044
1045	  This support is also available as a module.  If so, the module
1046	  will be called i2c-parport-light.
