Is WDMA different from MT8173 to MT2701. If they are the same, you need
not to add compatible of 'mediatek,mt2701-disp-wdma' because use
'mediatek,mt8173-disp-wdma' is enough.

Is DPI different from MT8173 to MT2701. If they are the same, you need
not to add compatible of 'mediatek,mt2701-dpi' because use
'mediatek,mt8173-dpi' is enough.

Is pwm different from MT8173 to MT2701. If they are the same, you need
not to add compatible of 'mediatek,mt2701-disp-pwm' because use
'mediatek,mt8173-disp-pwm' is enough.
