That's not really a reason on its own. Maybe the driver is wrong. Do we know what hardware needs this?

This means 'reset-names = "foo", "ahb";' is valid. You want 'items' instead. However, that still allows the below string in any order. Do we really need that? If not, then you want:
items: - const: stmmaceth - const: ahb
