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. Note that the MT8183 support is not ready to land yet because has some dependencies, i.e. mmsys support is still missing. So, only patches from 1 to 9 are ready, the others are provided for reference and test.
