hello, you need to use "rockchip,dummy-codec", example from dts

sai0-sound {
compatible = "rockchip,multicodecs-card";
rockchip,card-name = "sai0-tdm";
rockchip,format = "dsp_b";
rockchip,mclk-fs = <256>;
dai-tdm-slot-num = <8>;
dai-tdm-slot-width = <8>;
rockchip,cpu = <&sai0>;
rockchip ...

Thanks!!!

In rk3506g2 datasheet says that pwm has a capture mode.
Is this function implemented in drivers?
Thunks

Thanks

I need to use SAI as TDM mode for RK3506G2 Lyra Plus, but i did not find dts parameters...
