| 7 | The driver supersedes the older, never merged driver named i2c-nscacb. |
| 8 | |
| 9 | Module Parameters |
| 10 | ----------------- |
| 11 | |
| 12 | * base: up to 4 ints |
| 13 | Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices |
| 14 | |
| 15 | By default the driver uses two base addresses 0x820 and 0x840. |
| 16 | If you want only one base address, specify the second as 0 so as to |
| 17 | override this default. |
| 18 | |
| 19 | Description |
| 20 | ----------- |
| 21 | |
| 22 | Enable the use of the ACCESS.bus controller on the Geode SCx200 and |
| 23 | SC1100 processors and the CS5535 and CS5536 Geode companion devices. |
| 24 | |
| 25 | Device-specific notes |
| 26 | --------------------- |
| 27 | |
| 28 | The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820. |
| 29 | If the scx200_acb driver is built into the kernel, add the following |
| 30 | parameter to your boot command line:: |
| 31 | |
| 32 | scx200_acb.base=0x810,0x820 |
| 33 | |
| 34 | If the scx200_acb driver is built as a module, add the following line to |
| 35 | a configuration file in /etc/modprobe.d/ instead:: |
| 36 | |
| 37 | options scx200_acb base=0x810,0x820 |
