* power_supply: Add API for safe access of power supply function attrsKrzysztof Kozlowski2015-03-131-1/+46
| | | | | | | | | | | | | | | | | | | | | | Add simple wrappers for accessing power supply's function attributes: - get_property -> power_supply_get_property - set_property -> power_supply_set_property - property_is_writeable -> power_supply_property_is_writeable - external_power_changed -> power_supply_external_power_changed This API along with atomic usage counter adds a safe way of accessing a power supply from another driver. If power supply is unregistered after obtaining reference to it by some driver, then the API wrappers won't be executed in invalid (freed) context. Next patch changing the ownership of power supply class is still needed to fully fix race conditions in accessing freed power supply.

* power_supply: Move run-time configuration to separate structureKrzysztof Kozlowski2015-03-1359-150/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new structure 'power_supply_config' for holding run-time initialization data like of_node, supplies and private driver data. The power_supply_register() function is changed so all power supply drivers need updating. When registering the power supply this new 'power_supply_config' should be used instead of directly initializing 'struct power_supply'. This allows changing the ownership of power_supply structure from driver to the power supply core in next patches. When a driver does not use of_node or supplies then it should use NULL as config. If driver uses of_node or supplies then it should allocate config on stack and initialize it with proper values.

| | | | | | | | | | | | | | | | | | | | | | | | Allow drivers to store private data inside power_supply structure for later usage in power supply operations. Usage of driver private data is necessary to access driver's state container object from power supply calls (like get_property()) if struct 'power_supply' is a stored there as a pointer, for example: struct some_driver_info { struct i2c_client *client; struct power_supply *power_supply; ... } In such case one cannot use container_of() and must store pointer to state container as private data.

* ab8500_fg.c: only request threaded IRQs when necessaryValentin Rothberg2015-03-071-13/+33
| | | | | | | | | | | | | | | All 5 IRQ handlers of the driver are requested as threaded interrupt handlers. However, only 1 handler can block. The remaining 4 handlers defer the actual handling to a workqueue. Hence, 4 of 5 IRQ handlers have a considerable overhead, since they are executed in a kernel thread to schedule another kernel thread (workqueue). This change splits up the 5 interrupt handlers into top halves (_th) and bottom halves (_bh) and resolves the aforementioned overhead by only requesting threaded interrupts (i.e., bottom halves) when necessary.

| | | | | | | | Now that the driver doesn't use any ARM-specific headers, it is safe to build on MIPS or with COMPILE_TEST. Signed-off-by: Kevin Cernekee <cernekee@gmail.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
* power: charger-manager: Use alarmtimer for battery monitoring in suspend.Jonghwa Lee2015-01-212-208/+83
| | | | | | | | | | | | To guerantee proper charing and managing batteries even in suspend, charger-manager has used rtc device with rtc framework interface. However, it is better to use alarmtimer for cleaner and more appropriate operation. This patch makes driver to use alarmtimer for polling work in suspend and removes all deprecated codes related with using rtc interface.
