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.
