Andrew F. Davis 5ef6a16033 power: supply: bq27xxx: Add support for BQ27426
This device is software similar to the BQ27426 except it has
different data memory offsets. Add support here.

Pavel Machek 70a39e1075 Add support for bq27521 battery monitor
This adds basic support for BQ27521 battery monitor, used in Nokia N9
and N950. In particular, battery voltage is important to be able to
tell when the battery is almost empty. Emptying battery on N950 is
pretty painful, as flasher needs to be used to recover phone in such case.

Liam Breck 3a731c6414 power: supply: bq27xxx: Add chip IDs for previously shadowed chips
For the existing features, these chips act like others already ID'd,
so they had false but functional IDs. We will be adding features
which require correct IDs, so the following IDs are added:
BQ2752X, 531, 542, 546, 742, 425, 441, 621

Chip-specific features are now tracked by BQ27XXX_O_* flags in di->opts.

No functional changes to the driver.

The BQ27510 and BQ27520 use a slightly different register map than the
BQ27500, add a new type enum and add these gauges to it.

Sebastian Reichel 8c0984e5a7 power: move power supply drivers to power/supply
This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
