Subject: [PATCH v4 2/6] dt-bindings: hwmon: Move LM63 family to a dedicated binding
Date: Mon, 31 Aug 2026 21:45:36 +0800	[thread overview]
Message-ID: <20260831-ctl2301-v4-2-b335d52a0570@linux.dev> (raw)
In-Reply-To: <20260831-ctl2301-v4-0-b335d52a0570@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 preserve the optional interrupt used by the
ALERT output. Permit use as thermal cooling devices via #cooling-cells.
