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

  with version 2 of the TSENS IP. MSM8996 is the only exception because the

  generic property did not exist when support was added.

  Similarly, the generic "qcom,tsens-v1" property must be used as a fallback for

  any SoC with version 1 of the TSENS IP.
