Subject: [PATCH 00/14] POWER: BQ27x00: New Properties, fixes, bq27000 support

This patch series contains a few updates for the bq27x00 driver:
* Support for additional power supply properties
* Support for the bq27000 battery which is identical to the bq27200 but is
  connected through the HDQ bus.
* Adds a register cache to the driver and introduces polling the batteries state
* Minor improvements and cleanups

The last patch in this series is not specific to the bq27x00 driver but is
required for uevents to be generated properly for this driver.
The patch makes properties which return -ENODATA to be ignored when generating
uevents. Previously in such a case uevent generation would have been aborted
with an error. But since the bq27x00 return -ENODATA for the TIME_TO_FULL
property when the battery is not charging and for the TIME_TO_EMPTY property
when the battery is not discharging and at least one of them is always true
uevent generation would always fail.

This series has so far been tested with the bq27000 and the bq27200 battery, but
not with the bq27500 battery, so it would be nice if somebody with a board
containing such a battery could test the patches to make sure that there are no
regressions.
