The driver exists for the Enhanced Asynchronous Sample Rate Converter
(EASRC) Controller, but there isn't a device tree entry for it.
On the vendor kernel, they put this on a spba-bus for SDMA support.
Add the the node for the spba-bus with the easrc node inside.

The i.MX8M Nano supports the EASRC driver, and it requires ASRC.
Enable both of them as modules.

The i.MX8M Nano has supports the MICFIL digital interface.
It's a 16-bit audio signal from a PDM microphone bitstream.
The driver is already in the kernel, but the node is missing.
Add the micfil node.

Go ahead and disregard my V2. I'll submit a V3. I sent the V2 before
I got this feedback.

I just submitted a patch to document this bus. It's used on a bunch
of imx boards, so I think it's important to document it.
I assigned you as the maintainer of the binding doc since you're
listed as the maintainer of the SDMA driver which is what's using
the compatible flag. I hope that is the correct thing to do.
