In mt6595/mt8173, we have a hardware module named pwm. In mt2701, we have bls hardware module which includes disp pwm function, so we named it mt2701-disp-bls rather than mt2701-disp-pwm in order to match with hardware spec. thanks. > > > - "mediatek,mt6595-disp-pwm": found on mt6595 SoC. > > + - "mediatek,mt8173-disp-pwm": found on mt8173 SoC. > > - reg: physical base address and length of the controller's registers. > > - #pwm-cells: must be 2.
