Andreas Kemnade e92786dd86 power: supply: bd71828: sysfs for auto input current limitation
Add the possibility to disable the auto adjustment for input current
limitation via sysfs because it gives strange results under certain
circumstances e.g. when powering the device with solar panels
resulting in no input power usage at all.
