8 title: QCOM SoC Temperature Sensor (TSENS)
11   - Amit Kucheria <amitk@kernel.org>
14   QCOM SoCs have TSENS IP to allow temperature measurement. There are currently
16   The IP versions are named v0.1, v1 and v2 in the driver, where v0.1 captures
17   everything before v1 when there was no versioning information.
