The MAX1617A itself is actually supported by our "adm1021" driver for quite a long time now (since version 2.3.0 back in April 1999). What is probably not is the SMBus master itself.

Better stick to our model so you integrate with the existing layout and benefit from existing userspace support. What you need to do is to write a driver for your SMBus master chip, which respects the model we use. If your SMBus is bit-banging driven (and then most-likely I2C-compatible), take a look at i2c-voodoo3.c for an example (or any bus driver including i2c-algo-bit). If your SMBus is hardware-driver (and most probably not I2C-compatible) take a look at i2c-amd756.c instead (or any bus driver not including i2c-algo-bit). Once your bus driver is working, load it and run "sensors-detect", which should scan it and find the MAX1617A on it. -- Jean Delvare http://khali.linux-fr.org/
