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

  13 Module parameters:
  14
  15 * type: type of adapter (see i2c-parport or modinfo)
  16
  17 * base: base I/O address
  18   Default is 0x378 which is fairly common for parallel ports, at least on PC.
  19
  20 * irq: optional IRQ
  21   This must be passed if you want SMBus alert support, assuming your adapter
  22   actually supports this.
