          A serious problem is that there is no documented way to issue

          don't have clock stretching in transmission mode. For that reason,
          you can encounter underrun issues causing premature stop sendings if

          This supports parallel port I2C adapters such as the ones made by

          Basically any adapter using the parallel port as an I2C bus with
          no extra chipset is supported by this driver, or could be.

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

          An adapter type parameter is now mandatory.  Please read the file
          Documentation/i2c/busses/i2c-parport for details.

          Basically any adapter using the parallel port as an I2C bus with
          no extra chipset is supported by this driver, or could be.

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

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