From b0b349a85d3df00a40a8bd398e4a151fd8e91bbe Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 25 May 2011 20:43:33 +0200 Subject: hwmon: New driver for the SMSC EMC6W201 This is a new driver for the SMSC EMC6W201 hardware monitoring device. The device is functionally close to the EMC6D100 series, but is register-incompatible.

Note +that it is possible to control more than three fans by connecting two +fans to one PWM output. The EMC6W201 will be available in a 36-pin +QFN package." + +The device is functionally close to the EMC6D100 series, but is +register-incompatible. + +The driver currently only supports the monitoring of the voltages, +temperatures and fan speeds. Limits can be changed.
