  19 Datasheet: not publicly available, but seems to be similar to the
  20            AMD-8111 SMBus 2.0 adapter.

  27 Description
  28 -----------
  29
  30 i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
  31
  32 If your 'lspci -v' listing shows something like the following,
  33
  34 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
  35         Subsystem: Asustek Computer, Inc.: Unknown device 0c11
  36         Flags: 66Mhz, fast devsel, IRQ 5
  37         I/O ports at c000 [size=32]
  38         Capabilities: <available only to root>
  39
  40 then this driver should support the SMBuses of your motherboard.

  43 Notes
  44 -----
  45
  46 The SMBus adapter in the nForce2 chipset seems to be very similar to the
  47 SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get
  48 the driver to work with direct I/O access, which is different to the EC
  49 interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
  50 Asus A7N8X lists two SMBuses, both of which are supported by this driver.
