2 | * dme1737.c - Driver for the SMSC DME1737, Asus A8000, SMSC SCH311x and |
3 | * SCH5027 Super-I/O chips integrated hardware monitoring features. | |
4 | * Copyright (c) 2007, 2008 Juerg Haefliger <juergh@gmail.com> | |
9431996f | 5 | * |
e95c237d | 6 | * This driver is an I2C/ISA hybrid, meaning that it uses the I2C bus to access |
549edb83 JH |
7 | * the chip registers if a DME1737, A8000, or SCH5027 is found and the ISA bus |
8 | * if a SCH311x chip is found. Both types of chips have very similar hardware | |
e95c237d | 9 | * monitoring capabilities but differ in the way they can be accessed. |
