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. > +Optional properties: > +- interrupt-parent: Should be the phandle for the interrupt controller.
