After an attempt by MediaTek to upstream MT8186, MT8192 and MT8195 devicetrees, Krzysztof brought up a discussion in which it emerged that the usage of a 'simple-mfd' device is not an optimal choice for a number of reasons [1]. Reading that made me just write this simple code to stop nesting the SPM power-controller node inside of a "syscon", "simple-mfd" node, also allowing to move it outside of the main soc bus.
