Change subject: mb/lenovo/x200: Add ACPI methods to set battery thresholds ......................................................................
Patch Set 3:
Why don't you use existing interface to make coreboot compatible with tpacpi-bat and thinkpad_acpi? They use the following ACPI methods:
- BCCS
- BCSS
- BICS
- BDSS
- PSSS
They allow to set thresholds, inhibit charge, peak shift, ...
Now that I read the spec I think it's certainly possible to reimplement those at least partially.
