Changes in v4:
- Reword tsens commit message
- Add critical trip
- Link to v3: https://lore.kernel.org/r/20250226-expressatt-tsens-v3-0-bbf898dbec52@gmail.com

Changes in v3:
- Add signoff to dt-bindings commit
- Describe which values have been changed when copying over tsens from apq8064
- Drop wctrl as they want to remain anonymous. They have been CC'd as acknowledgement
- Link to v2: https://lore.kernel.org/r/20250226-expressatt-tsens-v2-0-7a4ce3a91f27@gmail.com

Changes in v2:
- Remove coefficients as it's read from EEPROM
- Fix dtsi formatting
- Fix dtschema warnings introduced with v1
- Link to v1: https://lore.kernel.org/r/20250225-expressatt-tsens-v1-1-024bee5f2047@gmail.com

[PATCH v4 2/2] ARM: dts: qcom: msm8960: Add thermal sensor (tsens)

[Rudraksha Gupta]

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.
