* link: Don't force battery to request currentRandall Spangler2012-10-241-6/+2
| | | | | | | | | | | | | | | | | | Previously, the battery charging algorithm would give the battery current even when it was requesting 0 mA. BUG=chrome-os-partner:15573 BRANCH=link TEST=charge battery and leave AC plugged in Battery will eventually drop to 99% charged. At that point, it should request 0mA, not 84mA or 85mA. (When it drops farther, it will really start requesting charge.)

* Rename battery pack file and limit trickle charging currentRong Chang2012-07-121-0/+126
The spec of link internal battery pack changed. This CL adds parameter for new pack, and renames vendor specific source file accordingly. The new trickle charging current limit should fix the slow pre-charging issue. Signed-off-by: Rong Chang <rongchang@chromium.org> BUG=chrome-os-partner:11298,10201 TEST=manual The minimum trickle charging current should be very close to 0.01 C (85mA). Previous battery pack firmware uses 5mA in pre- charging.
