This change adds a common part of smart battery driver. Following features are not implemented, or in chip specific driver: Battery access control, authentication, factory mode Manufacturer access/data commands Block read/write, device name, flash data Chip specific features, per cell info/temp/capacity Signed-off-by: Rong Chang <rongchang@google.com> BUG=chrome-os-partner:7856 TEST=console command check battery staus [unplug power] > battery [check voltage,current,capacity,time to empty] [plug power] > charger voltage 8400 > charger current 4250 > battery [check current,time to full] > charger input 4032 > battery [check current,time to full] [wait 130 seconds, charger watch dog timeout] > battery [check current] Change-Id: Ifac17a0892f52e8f37eebc14b00e71f18360776c Signed-off-by: Rong Chang <rongchang@chromium.org>
