Kernel driver scx200_acb¶
Author: Christer Weinigel <wingel@nano-system.com>
The driver supersedes the older, never merged driver named i2c-nscacb.
Module Parameters¶
- base: up to 4 ints Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices - By default the driver uses two base addresses 0x820 and 0x840. If you want only one base address, specify the second as 0 so as to override this default. 
Description¶
Enable the use of the ACCESS.bus controller on the Geode SCx200 and SC1100 processors and the CS5535 and CS5536 Geode companion devices.
Device-specific notes¶
The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820. If the scx200_acb driver is built into the kernel, add the following parameter to your boot command line:
scx200_acb.base=0x810,0x820
If the scx200_acb driver is built as a module, add the following line to a configuration file in /etc/modprobe.d/ instead:
options scx200_acb base=0x810,0x820
