920 Another driver exists, named i2c-parport-light, which doesn't depend
921 on the parport driver. This is meant for embedded systems. Don't say
922 Y here if you intend to say Y or M there.

4c03f68f 924 This support is also available as a module. If so, the module
f5b728a1 925 will be called i2c-parport.

932 This supports parallel port I2C adapters such as the ones made by
933 Philips or Velleman, Analog Devices evaluation boards, and more.
934 Basically any adapter using the parallel port as an I2C bus with
935 no extra chipset is supported by this driver, or could be.

937 This driver is a light version of i2c-parport. It doesn't depend
938 on the parport driver, and uses direct I/O access instead. This
939 might be preferred on embedded systems where wasting memory for
940 the clean but heavy parport handling is not an option. The
941 drawback is a reduced portability and the impossibility to
942 daisy-chain other parallel port devices.

944 Don't say Y here if you said Y or M to i2c-parport. Saying M to
945 both is possible but both modules should not be loaded at the same
946 time.
