Not NXP board, I could help fix, but that should not block this patchset.

There is no hidden issue. I removed "linux,code" from the tqma9596sa
board dts, and no warning with CHECK_DTBS.

More info:
This patchset does nothing with scmi_bbm nodes and bindings.
The warning triggered by the board which is not NXP
board(arch/arm64/boot/dts/freescale/imx95-tqma9596sa.dtsi).
This patchset does not touch that board dts.

What this patchset added is scmi_cpu and scmi_lmm nodes in
imx95.dtsi. The binding check already pass when I worked
on the scmi lmm/cpu protocol patchset.

Back to DTB check, by removing
linux,code = <KEY_BACK> from 
arch/arm64/boot/dts/freescale/imx95-tqma9596sa.dtsi,
there is no warning.
