 270           This driver is BROKEN because the controller which it uses
 271           will easily trigger RX overrun and TX underrun errors.  Using

 273           on some systems.  Another serious problem is that there is no

 548           Basically any adapter using the parallel port as an I2C bus with
 549           no extra chipset is supported by this driver, or could be.
 550
 551           This driver is a replacement for (and was inspired by) an older
 552           driver named i2c-philips-par.  The new driver supports more devices,
 553           and makes it easier to add support for new devices.
 554
 555           An adapter type parameter is now mandatory.  Please read the file
 556           Documentation/i2c/busses/i2c-parport for details.

 576           might be preferred on embedded systems where wasting memory for
 577           the clean but heavy parport handling is not an option.  The
 578           drawback is a reduced portability and the impossibility to
