I suppose it's better and more consistent to use the same hierarchy
pattern as Secure PWRC uses: to be a child of Secure Monitor.
Please see the example below from meson-a1.dtsi:
sm: secure-monitor {
compatible = "amlogic,meson-gxbb-sm";
pwrc: power-controller {
compatible = "amlogic,meson-a1-pwrc";
#power-domain-cells = <1>;
};
};
