-----BEGIN PGP SIGNED MESSAGE-----
This pair of patches add support for HDQ protocol batteries and the
bq27000 "coulomb counter" or "gas gauge" chip built into the battery.
Together you get an HDQ FIQ engine that talks to a bq27000 over one
GPIO and exposes it as a Linux power_supply class device.
Both patches create platform driver and devices with footprint in
/sys, the HDQ patch operates at the HDQ level without any understanding
of the semantics of the registers, while the bq27000 patch "knows" that
it is talking to a battery monitor and exposing the information over
a Linux power_supply class interface.
