[PATCH v2 09/12] arm64: dts: qcom: msm8994: Add PSCI node

From: Konrad Dybcio <hidden>
Date: 2020-06-23 22:49:12
Also in: linux-arm-msm, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

Add PSCI node to enable multi-processor startup.

Note that not every 8994 device firmware supports PSCI,
and even if, then it can only start the cores and not
shut them down.

Signed-off-by: Konrad Dybcio <redacted>
