Subject: [PATCH v3 1/6] Revert "arm64: dts: qcom: sm8450: Add PRNG"
Date: Mon, 28 Aug 2023 10:04:36 +0200	[thread overview]
Message-ID: <20230828-topic-sm8550-rng-v3-1-7a0678ca7988@linaro.org> (raw)
In-Reply-To: <20230828-topic-sm8550-rng-v3-0-7a0678ca7988@linaro.org>

This reverts commit 76a6dd7bfcbb ("arm64: dts: qcom: sm8450: Add PRNG"),
since the RNG HW on the SM8450 SoC is in fact a True Random Number Generator,
a more appropriate compatible should be instead as reported at [1].
