The i.MX8MP has an asynchronous sample rate converter which seems
to be the same as what is available on the i.MX8M Nano.

V3: No Change. The dt-binding update was already accepted into the sound tree, so that patch
was dropped from the series

Should the firmware name really be imx8mn or should it be imx8mp ?
I think the later is better, you can always add a symlink for the
firmware name, and you can discern mx8mn/mp firmwares on the same rootfs
in case that was ever needed in the future.
