It should work. You should just have to add the subsystem values to the dts
in the same way that it was added for the mainboard. You'll have to add
them in the mainboard's dts, though, or override the function that sets it.
If you add them in the device's dts they end up in the device_configuration
structure. That's part of the reason why the superio code ended up the way

Yeah. I like the dts. The strings from here go straight into statictree.c,
so anything that compiles there is fine.
