304	  Basically any adapter using the parallel port as an I2C bus with

306
307	  This driver is a replacement for (and was inspired by) an older
308	  driver named i2c-philips-par.  The new driver supports more devices,
309	  and makes it easier to add support for new devices.
310

330
331	  This driver is a light version of i2c-parport.  It doesn't depend
332	  on the parport driver, and uses direct I/O access instead.  This
333	  might be preferred on embedded systems where wasting memory for
334	  the clean but heavy parport handling is not an option.  The
335	  drawback is a reduced portability and the impossibility to
336	  daisy-chain other parallel port devices.
337
338	  Don't say Y here if you said Y or M to i2c-parport.  Saying M to
339	  both is possible but both modules should not be loaded at the same
