Subject: [PATCH v2 2/6] dt-bindings: hwmon: Move LM63 family to a dedicated binding
Date: Tue, 21 Jul 2026 02:48:28 -0700	[thread overview]
Message-ID: <20260721-ctl2301-v2-2-ef5fb342872a@linux.dev> (raw)
In-Reply-To: <20260721-ctl2301-v2-0-ef5fb342872a@linux.dev>

Move the National Semiconductor LM63, LM64, and LM96163 compatibles out
of trivial-devices.yaml and into a dedicated binding. Describe their
integrated fan control and permit use as thermal cooling devices through
the #cooling-cells property.
