Subject: [PATCH] arm64: dts: imx8mp: Correct thermal sensor index
Date: Fri, 05 Sep 2025 11:01:09 +0800 [thread overview]
Message-ID: <20250905-imx8mp-thermal-v1-1-64401ac8edb0@nxp.com> (raw)
The TMU has two temperature measurement sites located on the chip. The
probe 0 is located inside of the ANAMIX, while the probe 1 is located near
the ARM core. This has been confirmed by checking with HW design team and
checking RTL code.
So correct the {cpu,soc}-thermal sensor index.
Fixes: 30cdd62dce6b ("arm64: dts: imx8mp: Add thermal zones support")
