Subject: [PATCH v2 1/3] dt-bindings: thermal: samsung: Add tmu-name and sensor-index-ranges properties
Date: Wed, 3 Sep 2025 16:36:32 +0900 [thread overview]
Message-ID: <20250903073634.1898865-2-shin.son@samsung.com> (raw)
In-Reply-To: <20250903073634.1898865-1-shin.son@samsung.com>
The exynosautov920 TMU requires per-sensor interrupt enablement
for its critical trip points.
Add a DT property to the Samsung thermal bindings
to support this requirement:
- **samsung,hw-sensor-indices**: Defines the sensors currently
mapped to the TMU hardware.
Indices not listed are absent or fused off
Additionally, add myself to the bindings' maintainers list, as I plan
to actively work on the exynosautov920 TMU support and handle further
updates in this area.
