Subject[PATCH v2 7/7] arm64: dts: qcom: sc8280xp: add rng device tree node
Date
Add the necessary device tree node for qcom,prng-ee so we can use the
hardware random number generator. This functionality was tested on a
SA8540p automotive development board using kcapi-rng from libkcapi.

This is a new patch that's introduced in v2.
