[PATCH v4 0/2] Enable TSENS and thermal zone for QCS615 SoC

[PATCH v4 0/2] Enable TSENS and thermal zone for QCS615 SoC

[Gaurav Kohli]

Adding compatible string in TSENS dt-bindings, device node
for TSENS controller and Thermal zone support.

---
Changes in v4:
- Fix naming of thermal sensor.
- Link to v3: https://lore.kernel.org/linux-devicetree/20250613112402.2203617-1-quic_gkohli@quicinc.com/

Changes in v3:
- Add critical for all trips.
- Link to v2: https://lore.kernel.org/linux-devicetree/cover.1744955863.git.gkohli@qti.qualcomm.com/

Changes in v2:
- Drop the passive trip point and add critical for CPU thermal zones.
- Rearrange the tsens dt node and fix the address part.
- Fix the commit subject with target name.
- Link to v1: https://lore.kernel.org/linux-devicetree/cover.1744292503.git.quic_gkohli@quicinc.com/
