This should be the case only for common schemas used by other schemas.

Like iomuxc-gpr in patch 6, the problem is that for those nodes with
simple-mfd backwards compatibility,
there could be possibly some random subnodes since there're generic
combo registers.
That's why i use additionalProperties true to cover it.
Do you think it's ok?

No, because all that should be reviewed rather than random subnodes.
Otherwise, how do we validate them?
