I`m designing a base card for the imx8mm mini and i want to connect a digital mic using i2s.
this is how i plan to connect it:
is it ok? what do i need to add in the device tree in order for it to work?
The i.MX Pins Tool may help to setup the muxing options for your pins, and it allows to generate code for the Device Tree. You may download it from the link below:
More specifically speaking of setting up the device tree for I2S, the following threads may be able to help:

I2S microphone (SPH0645LM4H) Driver Implementation with i.mx6ul
I hope this helps!
