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
