Hello,
I'm working with a MIMXRT1170-EVKB and I'm quite new to working with Zephyr. It comes with 3 PDM Mics that are connected to the m7. It seems that the PDM controller of the m7 is not defined inside the Devicetree.
I'm a bit confused about the overall driver structure to use in Zephyr and I'm also new to writing Devicetree overlays. But my understanding is, that I need to define the PDM controller/DMIC and the corresponding pinmux/pinctrl settings in my board overlay file. I guess this would be compatible to the MICFIL driver ?
Has anyone experience in working with the PDM DMICs and might be able to give me some pointers if my understanding is correct or how to implement the PDM Mics?
