This patch allows reading and writing the input voltage and current limit through the POWER_SUPPLY_PROP_INPUT_VOLTAGE_LIMIT and POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT sysfs properties. This allows userspace to see current values and to re-configure these values at runtime based on system-level knowledge or user input. By default there is no limit, this is reported as a -1 when reading from userspace. Writing a value will set the current or voltage limit in uA or uV, and writing any negative value will remove that limit.
