Mika, _BIF method returns battery data/struct which is defined Table. 10-233.
If I want to pass some device specific data seems like I can use _DSM(9.14.1) method and pass custom /device specific data to the driver.
And I believe this data format can be anything and private to the device? Can you confirm?
