This required some driver refactoring of the axp20x USB and battery charger as the AXP717 is somewhat different but can still benefit from some common elements. Note that as of now the charging current now value may be incorrect as the scale and offsets were not documented in the datasheet. I suspect the scale is 1 and the offset is somewhere around 450mA though. Changes from V2: - Added constraints for input-current-limit-microamp constraints for x-powers,axp20x-usb-power-supply.yaml. - Used FIELD_GET() and removed unnecessary -EINVAL per comments from Jonathan Cameron. Changes from V1: - Refactored against mainline to remove BOOST pre-requisite. - Corrected commit subjects for DT bindings. - Split refactoring and AXP717 support into different patches. - Added IRQ for VBUS over voltage. There appears to be a bug with the VBUS fault IRQ because it is assigned IRQ num 0. - Corrected battery driver to report POWER_SUPPLY_PROP_VOLTAGE_MIN and POWER_SUPPLY_PROP_VOLTAGE_MAX instead of *_DESIGN.
