Subject: [PATCH v4 10/10] arm64: dts: qcom: sc8280xp: add rng device tree node
Date: Tue,  3 Jan 2023 13:22:29 -0500	[thread overview]
Message-ID: <20230103182229.37169-11-bmasney@redhat.com> (raw)
In-Reply-To: <20230103182229.37169-1-bmasney@redhat.com>

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.
