a=ed25519; pk=YJcXFcN1EWrzBYuiE2yi5Mn6WLn6L1H71J+f7X8fMag= Fuelgauge blocks often are incorporated in bigger chip, which may use only 1 line for interrupts. Shared-irq handles that case by requesting irq as shared. Maxim PMICs may include fuel gauge with additional features, which is out of single Linux power supply driver scope. For example, in max77705 PMIC fuelgauge has additional registers, like IIN_REG, VSYS_REG, ISYS_REG. Those needed to measure PMIC input current, system voltage and current respectively. Those measurements cannot be bound to any of fuelgauge properties. The solution here add and option to use max17042 driver as a MFD sub device, thus allowing any additional functionality be implemented as another sub device. This will help to reduce code duplication in MFD fuel gauge drivers. Make max17042 interrupt shared, and add platform driver version.
