Subject: [PATCH v3 3/6] crypto: qcom-rng - Add support for trng
Date: Mon, 28 Aug 2023 10:04:38 +0200	[thread overview]
Message-ID: <20230828-topic-sm8550-rng-v3-3-7a0678ca7988@linaro.org> (raw)
In-Reply-To: <20230828-topic-sm8550-rng-v3-0-7a0678ca7988@linaro.org>

The SM8450 & later SoCs RNG HW is now a True Random Number Generator
and a new compatible has been introduced to handle the difference.
