Apparently there was some confusion regarding milliohm vs. megaohm. (m/M). Use microohms to be able to properly specify the charger resistor like other drivers do. This is not used yet by mainline code yet. Specify a current sense resistor in milliohms range rathes then megaohms range in the examples.
