From 90905f7c40910a68677ea452ecf0023f31d6b08f Mon Sep 17 00:00:00 2001 From: Nick Hawkins Date: Tue, 3 Jan 2023 14:36:50 -0600 Subject: hwmon: (gxp-fan-ctrl) Add GXP fan controller The GXP SoC can support up to 16 fans through the interface provided by the CPLD. The current support is limited to 8 fans. The fans speeds are controlled via 8 different PWMs which can vary in value from 0-255. The fans are also capable of reporting if they have failed to the CPLD which in turn reports the status to the GXP SoC.
