Subject: [PATCH v4 2/2] ARM: dts: qcom: msm8960: Add thermal sensor (tsens)
Date: Thu, 27 Feb 2025 17:16:55 -0800	[thread overview]
Message-ID: <20250227-expressatt-tsens-v4-2-d70afa5a1fd0@gmail.com> (raw)
In-Reply-To: <20250227-expressatt-tsens-v4-0-d70afa5a1fd0@gmail.com>

Add support for the thermal sensor (tsens) on the MSM8960 by copying and
modifying the relevant nodes from the APQ8064 dtsi. These changes enable
thermal management.
