All, I looked through the SMSC sch311x datasheet and discovered that the HW monitoring capabilities of the two chips are nearly identical. The sch311x is missing some of the optional features like fan4 and pwmA and pwmB and registers are accessed through the LPC interface rather than an SMBus interface as is the case for the dme1737. So if I were to enhance the dme1737 driver to support the sch311x family this would imply that sch311x owners would also need to load i2c modules which aren't really necessary/used in this case. On the other hand, two separate drivers means a lot of code redundancy... Any thoughts on which way to go? Personally I prefer a single driver, way easier to maintain. Thanks ...juerg
