commit 75426a53b72aa8a0bdf39bd851daa7b9d4856f69 Author: Timothy Pearson tpearson@raptorengineeringinc.com Date: Sat Feb 21 01:46:20 2015 -0600
mainboard/asus/kfsn4-dre: Enable W83793 fan controller
The Winbond W83793 fan controller is not automatically configured correctly on power application, leading to abnormal, and in some cases random, fan behaviour.
This commit enables the controller and sets sane default values.
TEST: Booted mainboard and verified that the correct number of fan speed sensors were visible from hwmon under Linux. Also verified that, unlike before, the CPU fans were running at a high enough speed to properly cool the CPUs. Verified the 8 fan outputs under direct control of the W83793 device. Verified voltage and temperature sensors and limits via output of the 'sensors' command.
