That's not what I meant. The idea is to specify "lltc,ltc4100" with
"sbs,sbs-charger" as fallback. Then the driver for now only handles
"sbs,sbs-charger", but if any vendor registers need to be supported
we have a more specific compatible value in DT, that can be used to
identify the device.

So the example would look like
compatible = "lltc,ltc4100", "sbs,sbs-charger";
