Subject: [PATCH] dt-bindings: mfd: gateworks-gsc: Add fan-tach mode
Date: Mon, 28 Dec 2020 11:28:36 -0800 [thread overview]
Message-ID: <1609183716-26529-1-git-send-email-tharvey@gateworks.com> (raw)
In 7497d4a66c59 ("hwmon: (gsc-hwmon) add fan sensor") a mode
was added to report RPM's from a fan tach input.
Add this mode to the dt-bindings for the Gateworks System Controller.
