So what's the plan for this driver now? What's missing? Do you have
all the Acks you need? If so, I'm happy to apply this patch-set and
supply a pull-request to the other maintainers.

> ===========
> The MAX77836 is almost the same as MAX14577. Basically it is an extended
> version of MAX14577. The chipsets have same MUIC component so the extcon,
> charger and regulators require only little adjustments. More changes were
> needed in the charger (because it uses lower charging current) and regulator
> drivers (because mentioned different charing current and additional
> regulators). The MAX77836 has also PMIC and Fuel Gauge (which is the same
> as MAX17040/17048 Fuel Gauge).
> 
> The MAX77836 uses three I2C slave addresses and has additional interrupts
> (related to PMIC and Fuel Gauge). It has also Interrupt Source register,
> just like MAX77686 and MAX77693.
