Why? Commit must stand on its own.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

I see more usages. One more trivial patch which is incorrect.

Did you implement the internal review?

Please clean up AllOf also.

allOf:

- if:
properties:

contains:
enum:

^^^^
- fsl,imx8qm-edma

Patch2 was internal reviewed. Patch1 is new. I know you are busy. Could
you please give me 1 days to review nxp's patches. You see patch always
ahead me if author and you are in similar time zone.

I knew they are quite busy on heavy development work and all kinds
customer supports.
