Kernel driver i2c-nforce2 Supported adapters: * nForce2 MCP 10de:0064 * nForce2 Ultra 400 MCP 10de:0084 * nForce3 Pro150 MCP 10de:00D4 * nForce3 250Gb MCP 10de:00E4 * nForce4 MCP 10de:0052 * nForce4 MCP-04 10de:0034 Datasheet: not publically available, but seems to be similar to the AMD-8111 SMBus 2.0 adapter. Authors: Hans-Frieder Vogt <hfvogt@arcor.de>, Thomas Leibold <thomas@plx.com>, Patrick Dreker <patrick@dreker.de> Description ----------- i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP. If your 'lspci -v' listing shows something like the following, 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2) Subsystem: Asustek Computer, Inc.: Unknown device 0c11 Flags: 66Mhz, fast devsel, IRQ 5 I/O ports at c000 [size=32] Capabilities: <available only to root> then this driver should support the SMBuses of your motherboard. Notes ----- The SMBus adapter in the nForce2 chipset seems to be very similar to the SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get the driver to work with direct I/O access, which is different to the EC interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the Asus A7N8X lists two SMBuses, both of which are supported by this driver.
