This must follow what you just added to sunxi.yaml, so:
"bigtreetech,cb1-manta", "bigtreetech,cb1", "allwinner,sun50i-h616";
And you need the human readable "model" string *here*.

Extra empty line here.

Apart from the missing semicolon, which actually breaks the build (as you
have discovered yourself): there shouldn't be a model string in a .dtsi
file, that should be confined to the final board .dts, just as a human
readable form of the board compatible string. So drop this here, and add
the respective name to the two .dts files.
Rest looks fine now, thanks.
Cheers,
Andre
