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
|
|
the file /etc/modprobe.conf instead:
|
|
options scx200_acb base=0x810,0x820
