[PATCH V2 2/4] thermal/drivers/qcom: Add new feat for soc without rpm

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


In IPQ5018, Tsens IP doesn't have RPM. Hence the early init to
enable tsens would not be done. So add a flag for that in feat
and skip enable checks. Without this, tsens probe fails.

 [v2] Fixed the name for new tsens_feature without rpm
