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

5 7 Module Parameters
6 8 -----------------
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.

  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
