[PATCH v7 4/5] drivers: thermal: tsens: add IPQ8074 support

From: Robert Marko
Date: Thu Aug 18 2022 - 18:03:05 EST


Qualcomm IPQ8074 uses tsens v2.3 IP, however unlike other tsens v2 IP
it only has one IRQ, that is used for up/low as well as critical.
It also does not support negative trip temperatures.
