[v1] Add support for IPQ5018 tsens

[PATCH 6/7] arm64: dts: qcom: ipq5018: Add tsens node

Posted by Sricharan Ramabadhran 2 years, 3 months ago

IPQ5018 has tsens V1.0 IP with 4 sensors.
There is no RPM, so tsens has to manually enabled.
Adding the tsens and nvmem node.

NAK. Please define per-sensor fields here.

Nope. Come on, where do you see such node naming. Please do not send
code from downstream, but work on upstream sources. Open other most
recent DTS, take a look how it is done and try to do something similar.

compatible is always the first property. Then reg.
