Subject: [PATCH 1/2] dt-bindings: thermal: airoha: Allow sensor indices for EN7581
Date: Sat, 31 Oct 2026 16:19:11 +0200 [thread overview]
Message-ID: <20261031141912.1664575-2-sochnev.v.74@gmail.com> (raw)
In-Reply-To: <20261031141912.1664575-1-sochnev.v.74@gmail.com>
Allow either the existing zero-cell form or a sensor index that
selects the main or CPU ADC.
