From bd1e92f9977c78a04e9fe401e359feb67aacb7f9 Mon Sep 17 00:00:00 2001 From: Leonard Anderweit Date: Tue, 14 Feb 2023 23:02:21 +0100 Subject: hwmon: (aquacomputer_d5next) Add fan PWM control for Aquaero Add the option to control fan PWM on Aquacomputer Aquaero. The Aquaero is the most complex Aquacomputer device, control is therefore more complicated then on already supported devices. Setting PWM requires multiple steps. First, an internal static PWM controller is set to the desired PWM value. Second, the fan is set to use that PWM controller. Last, the minimum and maximum accepted PWM values of the fan are set to allow all possible PWM values.
