+ description: |
+ The maximum current to be drawn from the charger's input (in uA).
+ If this property is not specified, the input limit current is set
+ automatically using USB D+/D- signal based charger type detection.
+ If the hardware does not support the D+/D- based detection, a default
+ of 500,000 is used (=500mA) instead.
