The problem with that driver is that, in order to support more Mediatek SoCs you need to add some logic to handle properly the power-up sequence of newer Mediatek SoCs, doesn't handle parent-child power domains and need to hardcode all the clocks in the driver itself. The result is that the driver is getting bigger and bigger every time a new SoC needs to be supported. All this information can be getted from a properly defined binding, so can be cleaner and smaller, hence, we implemented a new driver. For now, only MT8173 and MT8183 is supported but should be fairly easy to add support for new SoCs.
