Tool/software: Linux
hello , i'm trying to activate the pcm1862 via i2c bus via commands from my raspberry pi 3 using pcm186x drivers . since no raspbian version supportes the pcm1862 i've created a customized distribution for the raspberry running on 5.1 linux kernel version since it supports pcm186x . after compiling the new kernel i ended up having the pcm186x modules compiled (snd-soc-pcm186x.ko and snd-soc-pcm186x-i2c.ko) under lib/modules/kernel/............/sound/soc/codecs . but i had to charge the modules into the kernel so that i can have them ready whenever booting the system. for that i added an audio overlay and converted it to.dtb in boot/overlays and edit the boot/config.txt . still when rebboting the pi and typing arecord -l nothing appears in the list . something must be missing in the sound node in the .dts file . here's the sound section in the overlay i've created .can you help me fix the problem ?
fragment@2 {
target = <&sound>;
sound_overlay: __overlay__ {
compatible ="simple-audio-card";
simple-audio-card,format = "i2s";
simple-audio-card,name = "pcm1862";
simple-audio-card,bitclock-master = <&dailink0_master>;
simple-audio-card,frame-master = <&dailink0_master>;
dai-tdm-slot-tx-mask = <1 1>;
dai-tdm-slot-rx-mask = <1 1>;
dai-tdm-slot-num = <2>;
dai-tdm-slot-width = <32>;
system-clock-frequency = <12288000>;
mclk-fs = <256>;
status = "okay";
simple-audio-card,cpu {
sound-dai = <&i2s>;
};
dailink0_master:simple-audio-card,codec {
sound-dai = <&pcm186x>;
};
};
};
__overrides__ {
card-name = <&sound_overlay>,"simple-audio-card,name";
};
