Subject: [PATCH 2/2] arm64: dts: exynos: gs101: add TRNG node
Date: Wed, 22 Oct 2025 11:19:36 +0000 [thread overview]
Message-ID: <20251022-gs101-trng-v1-2-8817e2d7a6fc@linaro.org> (raw)
In-Reply-To: <20251022-gs101-trng-v1-0-8817e2d7a6fc@linaro.org>
Define the TRNG node. GS101 TRNG works well with the current
Exynos850 TRNG support. Specify the Google specific compatible
in front of the Exynos one.
