From cdb8b7e1692a81f26030050ec30aadd2e7538fef Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Fri, 11 Aug 2023 22:50:57 +0200 Subject: [PATCH] crypto: qcom-rng: Make the core clock optional regardless of ACPI presence Some newer SoCs (like SM8450) do not require a clock vote for the PRNG to function. Make it entirely optional and rely on the bindings checker to ensure platforms that need it, consume one.
