From d2dd14ac1847082d4bb955619e86ed315c0ecd20 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sat, 28 Mar 2009 21:34:41 +0100 Subject: i2c-nforce2: Add support for MCP67, MCP73, MCP78S and MCP79 The MCP78S and MCP79 appear to be compatible with the previous nForce chips as far as the SMBus controller is concerned. The MCP67 and MCP73 were not tested yet but I'd be very surprised if they weren't compatible too.
