Implement a regulator driver with IRQ support for fault management.
Written against documentation [1] and [2] and tested on real hardware.
Every channel has its own regulator supplies nammed 'vss1-supply' and
'vss2-supply'. The regulator supply is used to determine the output
voltage, as the smart switch provides no output regulation.
The driver requires the 'shunt-resistor-micro-ohms' property to be
present in Device Tree to properly calculate current related
values.

Ignoring my comments won't make them go away. :)
Please tell me why you need a whole new driver, instead of adding
support to simple-mfd-i2c?
I felt current implementation to be simpler, clearer & straight forward.
If you can make it work with simple-mfd-i2c, please do so.
simple-mfd-i2c doesn't has mechanism to pass device type(max5978 vs
max5970).
No need to submit an entirely new driver for these simple use-cases.
