2009-07-02power_supply: Add a charge_type property, and use it for olpc driverAndres Salomon
This adds a new sysfs file called 'charge_type' which displays the type of charging (unknown, n/a, trickle charge, or fast charging). This allows things like battery diagnostics to determine what the battery/EC is doing without resorting to changing the 'status' sysfs output.

2009-06-30Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL"Andres Salomon
This reverts commit 8efe444038a205e79b38b7ad03878824901849a8 and 4cbc76eadf56399cd11fb736b33c53aec9caab8c. Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging battery/EC problems, and was upset that it was removed. This readds it.

2008-05-13power_supply: add CHARGE_COUNTER property and olpc_battery support for itAndres Salomon
This adds PROP_CHARGE_COUNTER to the power supply class (documenting it as well). The OLPC battery driver uses this for spitting out its ACR values (in uAh). We have some rounding errors (the data sheet claims 416.7, the math actually works out to 416.666667, so we're forced to choose between overflows or precision loss. I chose precision loss, and stuck w/ data sheet values), but I don't think anyone will care that much.
