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.
