From d468f825b3fddef9f844365073745cbd0e319e8d Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Mon, 4 Oct 2021 22:49:54 +0200 Subject: ARM: dts: qcom: msm8916: Add include for SMP without PSCI on ARM32 Add a special device tree include for MSM8916 on ARM32 that sets up SMP and cpuidle without PSCI. This is meant for devices with signed firmware that does not support PSCI and only allows booting ARM32 kernels.
