Subject: [PATCH v2 2/6] ABI: sysfs-class-hwmon: add a description for fanY_fault
Date: Mon, 28 Nov 2022 17:02:15 -0600	[thread overview]
Message-ID: <20221128230219.39537-3-nick.hawkins@hpe.com> (raw)
In-Reply-To: <20221128230219.39537-1-nick.hawkins@hpe.com>

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.
