hfvogt@gmx.net [PATCH] I2C i2c-nforce2: add support for nForce4 (patch against 2.6.11-rc4) ChangeSet 1.2105, 2005/03/02 12:18:53-08:00, hfvogt@gmx.net [PATCH] I2C i2c-nforce2: add support for nForce4 (patch against 2.6.11-rc4) can you please apply the attached patch (against 2.6.11-rc4, but works as well for 2.6.11-rc3-mm2), that adds support for the two SMBusses of the nForce4 to the i2c-nforce2 i2c bus driver. The patch is reported to work on the standard nForce4 (i.e. non-Ultra, non-SLI), but I expect that it works as well for the other nForce4 chipsets, that seem to have the same PCI-id for the SMBus-device. This patch was proposed by Chuck , thanks to him for the information, testing and his patch.
