[PATCH v2 20/24] dt: thermal: tsens: Add bindings for qcs404

From: Amit Kucheria
Date: Thu Feb 28 2019 - 07:28:05 EST


qcs404 uses v1 of the TSENS IP block. Create a fallback DT property
"qcom,tsens-v1" to gather common code

The generic "qcom,tsens-v2" property must be used as a fallback for any SoC
