HID: hid-input: add support for HID devices reporting Battery Strength
Some HID devices, such as my Bluetooth mouse, report their battery strength as an event. Rather than passing it through as a strange absolute input event, this patch registers it with the power_supply subsystem as a battery, so that the device's Battery Strength can be reported to usermode. The battery appears in sysfs names /sys/class/power_supply/hid-<UNIQ>-battery, and it is a child of the battery-containing device, so it should be clear what it's the battery of. Unfortunately on my current Fedora 16 system, while the battery does appear in the UI, it is listed as a Laptop Battery with 0% charge (since it ignores the "capacity" property of the battery and instead computes it from the "energy*" fields, which we can't supply given the limited information contained within the HID Report). Still, this patch is the first step. Signed-off-by: Jeremy Fitzhardinge <jeremy@goop.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
