Kernel driver i2c-parport-light

Author: Jean Delvare <khali@linux-fr.org> 

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.                 
  
Please see i2c-parport for documentation.

Module parameters:

* type: type of adapter (see i2c-parport or modinfo)

* base: base I/O address
  Default is 0x378 which is fairly common for parallel ports, at least on PC.

* irq: optional IRQ
  This must be passed if you want SMBus alert support, assuming your adapter
  actually supports this.
