Indeed, these SoC's have a lot in common, but as I can see the rk3308b has more blocks, like extra PWM's (rk3308 datasheet 1.5 [0] shows only 1x PWM 4ch, when rk3308b and rk3308b-s have 3x PWM 4ch), 1-wire and CAN controller (mentioned in the TRM, but dropped from rk3308b datasheet for some reason). So, in my view, it really makes sense to add rk3308b.dtsi, where extra PWM's, pinctrl compatible and its pin functions can be moved. And if its not worth it, then I will try to adapt the entire series to runtime config based on cpuid like you suggested. Additional thoughts on this would be appreciated.
