[PATCH v4 0/3] Enable IPQ9574 TSENS support

[Varadarajan Narayanan]

This patch set enables tsens in IPQ9574

Depends on
	https://lore.kernel.org/linux-arm-msm/20230406061314.10916-1-quic_devipriy@quicinc.com/
[v4]:
	Drop the sm6375-tsens and qcm2290-tsens related bindings
	fix as it is already posted

	Remove unnecessary changes from previous version

[v3]:
	Fix make DT_CHECKER_FLAGS=-m dt_binding_check and make dtbs_check errors

[v2]:
	Drop the driver change (https://lore.kernel.org/lkml/b45d33d38a334aabbd52c83b0d6028af1f4c74c8.1682682753.git.quic_varada@quicinc.com/)
	since the tsens device is compatible with 8074's tsens
	and use 8074's compatible itself

	Rename clusterX nodes as cpussX

[v1]:
	Fix DT node names

[v0]:
	Initial patch introducing TSENS support

Thanks for re-sending. I'm going to "ignore" this patch & Krzysztof can
take a look at it next week.

No, no need to move it to const. Was correct before.

Again, "-" means you remove a diff hunk. `man diff` and `man patch` (or
Wikipedia, dunno).

> +        items:
> +          - enum:

No, do not touch existing entry.

You need new item on entire list with two compatibles:

+        items:
+          - enum:
+              - qcom,ipq9574-tsens
+          - const: qcom,ipq8074-tsens

That's it. There should be no removal hunks in your diff (so one with "-").

Krzysztof
