Subject: [PATCH v2 7/7] arm64: dts: qcom: sc8280xp: add rng device tree node
Date: Wed, 14 Dec 2022 12:11:45 -0500 [thread overview]
Message-ID: <20221214171145.2913557-8-bmasney@redhat.com> (raw)
In-Reply-To: <20221214171145.2913557-1-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.
Signed-off-by: Brian Masney <bmasney@redhat.com>
