5 | +The driver supersedes the older, never merged driver named i2c-nscacb. | |

7 | 9 | |
8 | -* base: int | |
10 | +* base: up to 4 ints | |
9 | 11 | Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices |
10 | 12 | |
13 | + By default the driver uses two base addresses 0x820 and 0x840. | |
14 | + If you want only one base address, specify the second as 0 so as to | |
15 | + override this default. | |
16 | + | |
11 | 17 | Description |
12 | 18 | ----------- |
13 | 19 | |
14 | 20 | Enable the use of the ACCESS.bus controller on the Geode SCx200 and |
15 | 21 | SC1100 processors and the CS5535 and CS5536 Geode companion devices. |
22 | + | |
23 | +Device-specific notes | |
24 | +--------------------- | |
25 | + | |
26 | +The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820. | |
27 | +If the scx200_acb driver is built into the kernel, add the following | |
28 | +parameter to your boot command line: | |
29 | + scx200_acb.base=0x810,0x820 | |
30 | +If the scx200_acb driver is built as a module, add the following line to | |
31 | +the file /etc/modprobe.conf instead: | |
32 | + options scx200_acb base=0x810,0x820 |
