Hello, misc@!
I'm using ARM64/current and see that my audio chip got detected by simpleaudio
but OpenBSD can't attach audio to it
Any suggestions on there to start reading? I'm not developer,
but I tried to read different match/attach functions
in simpleaudio.c/audio.c with no result for now.
I got audio chip of my arm64 board
as
simpleaudio0 at mainbus0
eeprom says
Node 0x54f0

Looking at DTS I can identify it as Nuvoton Nau8822 sitting on i2c and/or i2s
nau8822@1a {
#sound-dai-cells = <0x01>;
compatible = "nuvoton,nau8822";
reg = <0x1a>;
phandle = <0x32>;
};
