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.

The firmware blobs provided by NXP only has easrc-imx8mn.bin and would be concerned that having a different name might confuse people if they try to go look for it and they only find easrc-imx8mn.bin.

To me, > this is no different than the SDMA driver using firmware called > sdma-imx7d.bin On the other hand, there is "fsl,imx8mp-easrc" compatible string -- to differentiate between IPs in case some difference between the IPs that cannot be predicted so far is found later on. >> 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. Which is what this part of my comment ^ is all about.

The i.MX8MP has an asynchronous sample rate converter which seems to be the same as what is available on the i.MX8M Nano. Signed-off-by: Adam Ford <aford173@gmail.com> --- V3: No Change. The dt-binding update was already accepted into the sound tree, so that patch was dropped from the series V2: No Change.
