Marcel,
This would break imx8mm-venice.
The of-list, @fdt-SEQ and @config-SEQ are required to support
automatic generation of fdt and config nodes when you have multiple
device-trees. See tools/binman/entries.rst for details.
Currently, imx8mm-venice is the only board that uses multiple dtbs in
CONFIG_OF_LIST so this would be the only board broken by your patch.
I'm curious if just using the of-list, @fdt-SEQ and @config-SEQ as
above works fine for boards with a single dtb? Otherwise I suppose
boards like mine can include your common "imx8mm-binman.dtsi" but will
have to leave the &binman node override.
Best regards,
Tim
