This patch uses the new battery hooking API to add
support for the ACPI battery wear control present in
Lenovo ThinkPads that have >=SandyBridge processors.
thinkpad_acpi registers two new attributes for each battery:
1) Charge start threshold
/sys/class/power_supply/BATN/charge_start_threshold
The EC/ACPI firmware on Lenovo ThinkPads used to report a status
of "Unknown" when the battery is between the charge start and
charge stop thresholds. On Windows, it reports "Not Charging"
so the quirk has been added to also report correctly.
Now the "status" attribute returns "Not Charging" when
This is a patch that implements a generic hooking API for the
generic ACPI battery driver.
With this new generic API, drivers can expose platform specific
behaviour via sysfs attributes in /sys/class/power_supply/BATn/
in a generic way.
A perfect example of the need for this API are Lenovo ThinkP
