That's still not correct patch format.

> Subject: [PATCH] Add dts to support MAX98090/91 with i.MX8MM-evk

That's still not correct subject. You already got this comment and
ignored it.

Your recipient list is enormous. Use get_maintainers.pl. You already got
this comment and ignored it.

If you intend to ignore all the comments, then this is NAK.

This is v2? Patch subject should be marked with it. You need to add
changelog.

Why? Explain what you want to achieve and why do you do it.

That's a dead code without Makefile.

Missing bindings.

You either ignored the comment or misread it. Go back to previous code.

This is no way working... Test your code against bindings. Please run
`make dtbs_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
