| 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 | prefered 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. |

| 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. |
