  1. Kernel driver i2c-nforce2
  2. Supported adapters:
  3. * nForce2 MCP 10de:0064
  4. * nForce2 Ultra 400 MCP 10de:0084
  5. * nForce3 Pro150 MCP 10de:00D4
  6. * nForce3 250Gb MCP 10de:00E4
  7. * nForce4 MCP 10de:0052
  8. Datasheet: not publically available, but seems to be similar to the
  9. AMD-8111 SMBus 2.0 adapter.

  14. Description
  15. -----------
  16. i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
  17. If your 'lspci -v' listing shows something like the following,
  18. 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
  19. Subsystem: Asustek Computer, Inc.: Unknown device 0c11
  20. Flags: 66Mhz, fast devsel, IRQ 5
  21. I/O ports at c000 [size=32]
  22. Capabilities: <available only to root>
  23. then this driver should support the SMBuses of your motherboard.
  24. Notes
  25. -----
  26. The SMBus adapter in the nForce2 chipset seems to be very similar to the
  27. SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get
  28. the driver to work with direct I/O access, which is different to the EC
  29. interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
  30. Asus A7N8X lists two SMBuses, both of which are supported by this driver.
