Subject: [PATCH v2 4/7] arm64: dts: freescale: imx95: add anamix temperature thermal zone and cooling node
Date: Tue, 03 Sep 2024 15:17:49 +0800 [thread overview]
Message-ID: <20240903-imx95-dts-new-v2-4-8ed795d61358@nxp.com> (raw)
In-Reply-To: <20240903-imx95-dts-new-v2-0-8ed795d61358@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
i.MX95 has two on-chip temperature sensors, one is inside anamix block.
This is to add the anamix temperature thermal zone and its cooling
device.
