* isp1704_charger: Add DT supportSebastian Reichel2013-12-231-0/+1
| | | | | | | | | This patch introduces device tree support to the isp1704 charger driver. Adding support involved moving the handling of the enable GPIO from board code into the driver. Signed-off-by: Sebastian Reichel <sre@debian.org> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
* bq2415x_charger: Use power_supply notifier for automodePali Rohár2013-12-231-43/+5
| | | | | | | | | | | | This patch removing set_mode_hook function from board data and replacing it with new string variable of notifier power supply device. After this change it is possible to add DT support because driver does not need specific board function anymore. Only static data and name of power supply device is required.

* charger-manager: Modify the way of checking battery's temperatureJonghwa Lee2013-12-231-8/+16
| | | | | | | | | | | | | | | | | | | Charger-manager driver used to check battery temperature through the callback function passed by platform data. Unfortunatley, without that pre-defined callback function, charger-manager can't get battery's temperature at all. Also passing callback function through platform data ruins DT support for charger-manager. This patch mondifies charger-manager driver to get temperature of battery without pre-defined callback function. Now, charger-manager can use either of battery thermometer in fuel-gauge and ouside of battery. It uses thermal framework interface for outer thermometer if thermal fw is enabled. Otherwise, it tries to use fuel-gauge's through the power supply interface.

* bq24190_charger: Add support for TI BQ24190 Battery ChargerMark A. Greer2013-08-271-0/+16
| | | | | | | | | | | | | | | | Add driver support for the Texas Instruments BQ24190 battery charger. Some of the information provided by the device is about the charger and other information is about the battery so create two power_supply objects (one for each) and provide the appropriate information for each one. The device has many fields that go beyond what is reasonable to report or modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver exports the register fields via sysfs. They are prefixed by 'f_' (for 'field') to make it easier to distinguish between a register field and a "normal" sysfs file exported by the power_supply infrastructure. Signed-off-by: Mark A.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SmartReflex driver incorrectly treats some per-OPP data as data common to all OPPs (e.g., ERRMINLIMIT). Move this data into a per-OPP data structure. Furthermore, in order to make the SmartReflex implementation ready for the move to drivers/, remove the dependency from the SR driver code to the voltage layer by querying the data tables only from the SR device init code.
