Newly added i2s device returns error at kernel startup: "[ 2.359377] st,stm32-i2s 44004000.audio-controller: no irq for node 44004000.audio-controller" [Answered]
Hello,
so I am using the Yocto environment and patched the device tree:

#address-cells = <1>;And basically I just want to add a new I2S sound device to connect to via the GPIOs to evaluate data.
The patch gets deployed with no problems. However I am getting the Error
[ 2.359377] st,stm32-i2s 44004000.audio-controller: no irq for node 44004000.audio-controller
What is it that I am missing?
