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.                 
10	  
11	Please see i2c-parport for documentation.
12	
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.
