| 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. |
