  10 Datasheet: not publically available, but seems to be similar to the
  11            AMD-8111 SMBus 2.0 adapter.

  18 Description
  19 -----------
  20
  21 i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
  22
  23 If your 'lspci -v' listing shows something like the following,
  24
  25 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
  26         Subsystem: Asustek Computer, Inc.: Unknown device 0c11
  27         Flags: 66Mhz, fast devsel, IRQ 5
  28         I/O ports at c000 [size=32]
  29         Capabilities: <available only to root>
  30
  31 then this driver should support the SMBuses of your motherboard.

  34 Notes
  35 -----
  36
  37 The SMBus adapter in the nForce2 chipset seems to be very similar to the
  38 SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get
  39 the driver to work with direct I/O access, which is different to the EC
  40 interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
  41 Asus A7N8X lists two SMBuses, both of which are supported by this driver.
