The shunt resistance can only be set via platform_data or device tree. This isn't suitable for devices in which the shunt resistance can change/isn't known at boot-time. Add a sysfs attribute that allows to read and set the shunt resistance.

After reading the datasheet again ... those defines were meant to reflect registers, not to create 'dummy' index values for software. Please rearrange your code to not require such constructs; it is just confusing for others (including me).
