Subject: [PATCH 2/3] arm64: dts: qcom: msm8937: change prng compatible
Date: Thu, 01 Oct 2026 07:51:39 +0200 [thread overview]
Message-ID: <20261001-prng-fix-v1-2-72f924527465@mainlining.org> (raw)
In-Reply-To: <20261001-prng-fix-v1-0-72f924527465@mainlining.org>
On MSM8937 HW QRNG is configured by TZ. qcom-rng driver
will not have access to the configuration registers.
Change the compatible to qcom,prng-ee for skip the initialization sequence.
Fixes: a829f6f2e8a7 ("arm64: dts: qcom: Add initial support for MSM8937")
