From 41e9a062361de204d3710038925ae7f356ebb40d Mon Sep 17 00:00:00 2001 From: Daniel J Blueman Date: Mon, 14 Dec 2009 18:01:37 -0800 Subject: hwmon: w83627ehf updates Add control of fan minimum turn-on output levels, decoupling it from the fan turn-off output level. Add control of rate of change of fan output level. These in turn allow lower turn-off rotor speed and smoother transitions for better thermal and acoustic control authority. Add support for constant fan speed and proportional-response operations modes.
