[PATCH v4 2/6] dt-bindings: hwmon: Move LM63 family to a dedicated binding
From: Troy Mitchell <hidden>
Date: 2026-08-31 13:46:27

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.
