+What: /sys/class/power_supply/twl4030_ac/max_current
+ /sys/class/power_supply/twl4030_usb/max_current
+Description:
+ Read/Write limit on current which may
+ be drawn from the ac (Accessory Charger) or
+ USB port.
+
+ Value is in micro-Amps.
+
+ Value is set automatically to an appropriate
+ value when a cable is plugged or unplugged.
+
+ Value can the set by writing to the attribute.
+ The change will only persist until the next
+ plug event. These event are reported via udev.
+
+
+What: /sys/class/power_supply/twl4030_usb/mode
+Description:
+ Changing mode for USB port.
+ Writing to this can disable charging.
+
+ Possible values are:
+ "auto" - draw power as appropriate for detected
+ power source and battery status.
+ "off" - do not draw any power.
+ "continuous"
+ - activate mode described as "linear" in
+ TWL data sheets. This uses whatever
+ current is available and doesn't switch off
+ when voltage drops.
+
+ This is useful for unstable power sources
+ such as bicycle dynamo, but care should
+ be taken that battery is not over-charged.
+
+What: /sys/class/power_supply/twl4030_ac/mode
+Description:
+ Changing mode for 'ac' port.
+ Writing to this can disable charging.
+
+ Possible values are:
+ "auto" - draw power as appropriate for detected
+ power source and battery status.
+ "off" - do not draw any power.
