In the SoC before, such as mt8173, it has 2 pipelines binding to one mmsys with the same clock driver and the same power domain. In mt8195, there are 4 pipelines binding to 4 different mmsys, such as vdosys0, vdosys1, vppsys0 and vppsys1. Each mmsys uses different clock drivers and different power domain. Since each mmsys has its own clock, they could be identified by the different name of their clock.
