[PATCH 0/2] Make standalone compatible for IPQ5018 tsens v1 without RPM

[PATCH 0/2] Make standalone compatible for IPQ5018 tsens v1 without RPM

[George Moussalem via B4 Relay]

The tsens IP found in the IPQ5018 SoC should not use qcom,tsens-v1 as
fallback since it has no RPM and, as such, must deviate from the
standard v1 init routine as this version of tsens needs to be explicitly
reset and enabled in the driver.

Accordingly, update the tsens node in the IPQ5018 dts and remove the
fallback compatible.

Additional background: this was already incorporated in the patch series
which added support for IPQ5018 tsens initially. V9 was applied while
v13 had already been sent for review. In agreement with Bjorn Andersson,
I've submitted this new patch set to correct the issue.

I have taken the liberty to re-apply RB tags provided by Krzysztof,
Konrad, and Dmitry from:

[PATCH 1/2] dt-bindings: thermal: qcom-tsens: make ipq5018 tsens standalone compatible

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@outlook.com>

The tsens IP found in the IPQ5018 SoC should not use qcom,tsens-v1 as
fallback since it has no RPM and, as such, must deviate from the
standard v1 init routine as this version of tsens needs to be explicitly
reset and enabled in the driver.

So let's make qcom,ipq5018-tsens a standalone compatible in the bindings.

[PATCH 2/2] arm64: dts: qcom: ipq5018: Remove tsens v1 fallback compatible

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@outlook.com>

Remove qcom,tsens-v1 as fallback compatible since this IP has no RPM
and, as such, must use its own init routine available in the driver.
