To explain more:
In the few Maxim PMIC/MUIC charger designs known to me, the fuel gauge
is a separate device. In all implementations it is even on separate bus,
although does not have to. You claim that this is not a separate device
and you even claim that this *MUST* be on the same bus.

Both claims sound just wrong, IMO. This needs explanation. It seems you
develop bindings just to match your drivers and that is not the correct
process. Bindings must match the hardware, not your driver architecture.


Best regards,
Krzysztof
