power: supply: ug3105_battery: Add driver for uPI uG3105 battery monitor
Add a new battery driver for the uPI uG3105 battery monitor.
Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead it
is expected to be use in combination with some always on microcontroller
reading its coulomb-counter before it can wrap (must be read every 400
seconds!).
Since Linux does not monitor coulomb-counter changes while the device is
off or suspended, the coulomb counter is not used atm.
So far this driver is only used on x86/ACPI (non devicetree) devs
(also note there is no of_match table). Therefor there is no devicetree
bindings documentation for this driver's "upisemi,rsns-microohm" property
since this is not used in actual devicetree files and the dt bindings
maintainers have requested properties with no actual dt users to
_not_ be added to the dt bindings.
The property's name has been chosen so that it should not need to be
changed if/when devicetree enumeration support gets added later, as it
mirrors "maxim,rsns-microohm" from the "maxim,max17042" bindings.
