[PATCH v1 2/6] ABI: sysfs-class-hwmon: add a description for fanY_fault

From: nick.hawkins@hpe.com
Date: 2022-11-04 19:39:18
Also in: linux-devicetree, linux-doc, linux-hwmon, lkml
Subsystem: hardware monitoring, the rest · Maintainers: Guenter Roeck, Linus Torvalds

From: Nick Hawkins <nick.hawkins@hpe.com>

The fans are capable of reporting a fault to the CPLD controller which
then reports it to the GXP SoC via PLREGS. This patch enables hwmon to
be able to report these failures up to the HOST OS.
