| 14 | QCOM SoCs have TSENS IP to allow temperature measurement. There are currently |
| 15 | three distinct major versions of the IP that is supported by a single driver. |
| 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. |
