[ Upstream commit a22f9a766e1dc61f8f6ee2edfe83d4d23d78e059 ]
Add the device tree nodes necessary for SMP bring-up and cpuidle without PSCI on ARM32. The hardware is typically controlled by the PSCI implementation in the TrustZone firmware and is therefore marked as status = "reserved" by default (from the device tree specification):
"Indicates that the device is operational, but should not be used. Typically this is used for devices that are controlled by another software component, such as platform firmware."
Since this is part of the MSM8916 SoC it should be added to msm8916.dtsi but in practice these nodes should only get enabled via an extra include on ARM32.
This is necessary for some devices with signed firmware which is missing both ARM64 and PSCI support and can therefore only boot ARM32 kernels.

This patch is not useful without other changes that landed in 5.16 (in particular, the new device actually making use of these nodes).
Can you drop this patch?
Thanks, Stephan
