2016-09-05power: supply: bq24735-charger: Request status GPIO with initial input setupPaul Kocialkowski2-31/+12
This requests the status GPIO with initial input setup. It is required to read the GPIO status at probe time and thus correctly avoid sending I2C messages when AC is not plugged. When requesting the GPIO without initial input setup, it always reads 0 which causes probe to fail as it assumes the charger is connected, sends I2C messages and fails. While at it, this switches the driver over to gpiod API. Signed-off-by: Paul Kocialkowski <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
2016-09-01power: supply: sbs-battery: Use gpio_desc and sleeping calls for battery detectPhil Reid2-71/+34
Switch to using new gpio_desc interface and devm gpio get calls to automatically manage gpio resource. Use gpiod_get_value which handles active high / low calls. If gpio_detect is set then force loading of the driver as it is reasonable to assume that the battery may not be present. Update the is_present flag immediately in the IRQ. Remove legacy gpio specification from platform data. Signed-off-by: Phil Reid <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>

Due the driver improvements, update the properties, - Remove "active-semi,check-battery-temperature" property. - Add the properties, "active-semi,irq_gpio" and "active-semi,lbo-gpios". - As act8945a-charger is regarded as a sub-device, update the compatible and examples.

2016-08-31power: supply: act8945a_charger: Add status change update supportWenyou Yang1-7/+88
Add the charger status change interrupt support, it will report the power supply changed event. This interrupt is generated by one of the conditions as below: - the state machine jumps out of or into the EOC state - the CHGIN input voltage goes out of or into the valid range. - the battery temperature goes out of or into the valid range. - the PRECHARGE time-out occurs. - the total charge time-out occurs.

2016-08-29power: bq24735-charger: Assume not charging when charger is missingPaul Kocialkowski1-1/+5
When the charger is missing (disconnected), it is safe to assume that the charger chip is no charging. This is especially relevant when a status GPIO is present and the charger is getting disconnected. bq24735_charger_is_charging will be triggered due to the interrupt then, it will attempt to read whether it is charging through i2c, which will fail as the charger is disconnected. This also fixes that specific issue. Signed-off-by: Paul Kocialkowski <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>

2016-08-16power: ds2760_battery: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-1/+2
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces deprecated create_singlethread_workqueue(). This is the identity conversion. The workqueue "monitor_wqueue" is used to monitor the battery status. It has been identity converted. It queues multiple work items viz &di->monitor_work, &di->set_charged_work, which require execution ordering. Hence, alloc_workqueue has been used to replace the deprecated create_singlethread_workqueue instance. WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure.

The workqueue "fg_wq" is used for running the FG algorithm periodically. It has been identity converted. It has multiple work items viz fg_periodic_work, fg_low_bat_work, fg_reinit_work, fg_work, fg_acc_cur_work and fg_check_hw_failure_work, which require execution ordering.

The workqueue "charger_wq" is used for running all the charger related tasks. This involves charger detection, checking for HW failure and HW status. This workqueue has been identity converted. It queues multiple workitems viz &pm2->check_main_thermal_prot_work, &pm2->check_hw_failure_work, &pm2->ac_work.
