+Subject: [PATCH] arm64: dts: qcom: ipq6018: use CPUFreq NVMEM
+
+IPQ6018 comes in multiple SKU-s and some of them dont support all of the
+OPP-s that are current set, so lets utilize CPUFreq NVMEM to allow only
+supported OPP-s based on the SoC dynamically.
+
+As an example, IPQ6018 is generaly rated at 1.8GHz but some silicon only
+goes up to 1.5GHz and is marked as such via an eFuse.
