Basically you have two nodes which both bind to mediatek,mt7623-mmsys. The only difference here is, that your clock drivers is a builtin_platform_driver while on mt8173 it get's probed earlier as it is defined as CLK_OF_DECLARE. Do you see both drivers getting probed? I don't have my mt7623 board at hand right now to check this. In any case, please wait until we found a way to fix the issue before we add these bindings.
