Sorry, I couldn't understand this.
Do you mean like this ?
This example is assuming like this, and shows FSI-ak4642 sound
FSI port A -- ak4642
port B -- HDMI
sh_fsi2 has #sound-dai-cells, and ak4642 doesn't have it.
Does this solved a) ?
Do you mean sh_fsi2 needs something like "port-a = xxx" settings for b) ??
sound {
compatible = "simple-audio";
simple-audio,card-name = "FSI2A-AK4648";
simple-audio,format = "left_j";
simple-audio,cpu,dai = <&sh_fsi2 0>;
simple-audio,codec,dai = <&ak4648>;
simple-audio,codec,bitclock-master;
simple-audio,codec,frame-master;
simple-audio,codec,system-clock-frequency = <11289600>;
};
&i2c0 {
ak4648: ak4648@0x12 {
compatible = "asahi-kasei,ak4648";
reg = <0x12>;
};
};
sh_fsi2: sh_fsi2@0xec230000 {
#sound-dai-cells = <2>;
compatible = "renesas,sh_fsi2";
reg = <0xec230000 0x400>;
interrupt-parent = <&gic>;
interrupts = <0 146 0x4>;
};
Best regards
