Subject: [PATCH 0/3] Add QFPROM support for few IPQ SoCs

Like any other SOCs, Qualcomm's IPQ SOCs also have an efuse region which
exposes the HW quirks like CPU Freq limit and so on. This series add the
basic support for the efuse. Feature specific fuses will be added along
with the feature set.

Subject: [PATCH 3/4] arm64: dts: qcom: ipq6018: add QFPROM node

IPQ6018 has efuse region to determine the various HW quirks. Lets
add the initial support and the individual fuses will be added as they
are required.

This should be a bit lower down (0xa4000 > 0x59000)
