QCOM SoCs have TSENS IP to allow temperature measurement. There are currently
|
|
three distinct major versions of the IP that is supported by a single driver.
|
|
The IP versions are named v0.1, v1 and v2 in the driver, where v0.1 captures
|
|
everything before v1 when there was no versioning information.
