I think this wording is a bit better: - ti,current-limit: 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. -- Sebastian
