I think it's fine to keep it here, as the regulator (U59) that generates
5V from 12V is present on the Kingfisher board. However, according
to the schematics, 5V is generated by the PMIC on the ULCB too, and
both 5V nets are connected through the board-to-board connectors?

i.e. will queue in renesas-devel for v6.9.
