Subject: [PATCH v2 14/15] ARM: dts: qcom: msm8916: Add include for SMP without PSCI on ARM32
Date: Mon, 4 Oct 2021 22:49:54 +0200 [thread overview]
Message-ID: <20211004204955.21077-14-stephan@gerhold.net> (raw)
In-Reply-To: <20211004201921.18526-1-stephan@gerhold.net>
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.
Signed-off-by: Stephan Gerhold <stephan@gerhold.net>
