From c684d05b0fa66f86b3c94ecd46388858d8e5dcaa Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Sat, 21 Feb 2015 01:46:20 -0600 Subject: 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.
