[PATCH v2 4/7] arm64: dts: freescale: imx95: add anamix temperature thermal zone and cooling node
Posted by Peng Fan (OSS) 1 year, 3 months ago
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.
