Subject: [PATCH 2/2] arm64: dts: imx95-tqma9596sa: Add thermal zones
Date: Mon, 28 Sep 2026 13:21:42 +0200	[thread overview]
Message-ID: <20260928112143.294091-2-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20260928112143.294091-1-alexander.stein@ew.tq-group.com>

These PMIC sensors are provided by the SCMI firmware and are independent
from the mainboard.
