[v2] Add QFPROM support for few IPQ SoCs

[PATCH V2 3/4] arm64: dts: qcom: ipq6018: add QFPROM node

Posted by Kathiravan T 1 year, 10 months ago

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.

It looks like the prng node name is incorrect. It should be qrng@e3000
instead of qrng@e1000. Could you please send a followup to fix it?
