I don't know the board you are using. But you need to have a AC driver to register with power_supply_core to create the AC0 or ac directory. For X86, we drivers/acpi/ac.c. You can also look at drivers/power/goldfish_battery.c and look for power_supply_register(&pdev->dev, &data->ac) Yi On Mon, 2009-04-27 at 08:03 +0400, Elvis Dowson wrote: > Hi, > The board that I have is an Overo Earth with Palo43 expansion > board.
