> The clock for which all PWM devices on MT7623 or MT2701 actually depending
> on has to be divided by four from its parent clock axi_sel in the clock
> path prior to PWM devices.
>
> Consequently, adding a fixed-factor clock axisel_d4 as one-fourth of
> clock axi_sel allows that PWM devices can have the correct resolution
> calculation.
