From b294a290d24d1196d68399cc3a9b8c50bfb55abd Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Tue, 30 Jun 2009 02:13:01 -0400 Subject: Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL" 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.

This allows things like battery diagnostics to determine what the battery/EC is doing without resorting to changing the 'status' sysfs output.

It also includes functions to get a power_supply device from the class of registered devices by name reference. These can be used to find a specific battery to call power_supply_set_battery_charged() on. Some battery drivers might need this information to calibrate themselves.
