It is not power controller. rcpm controller enable wakeup source. In arm64, use below patch to fix warning commit e39f567e1c38c29629962ab327f0ad1a288dcab2 Author: Frank Li <frank...@nxp.com> Date: Mon Jul 29 14:59:24 2024 -0400 arm64: dts: layerscape: rename rcpm as wakeup-control from power-control Invoke power-domain.yaml if node name as 'power-control'. Rcpm actually are not power domain controller. It just control wakeup capability. So rename it as wakeup-control.
