* mfd: pcf50633: Remove #ifdef guards for PM related functionsPaul Cercueil2022-12-071-4/+2
| | | | | | | | | | | | | | | | Use the new EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

| * pcf50633: Get rid of charging restart software auto-triggeringPaul Fertser2009-11-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
| * pcf50633: introduces battery charging current controlBalaji Rao2009-11-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new sysfs attribute to allow changing MBC charging limit on the fly independently of usb current limit. It also gets set automatically every time usb current limit is changed. Limiting charging current also prevents violating USB specification in the case when the whole device is shut down and usb current limit is reset to the factory default by the pcf50633 state transition.

* | mfd: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen2009-12-131-5/+5
|/ | | | | | | | | | | | | Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

* mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser2009-09-171-0/+1
| | | | | | | | | | | | | | Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

* pcf50633_charger: Enable periodic charging restartBalaji Rao2009-02-021-0/+2
| | | | | | | | | | | | | | | The battery charger state machine switches into charging mode when the battery voltage falls below 96% of a battery float voltage. But the voltage drop in Li-ion batteries is marginal(1~2 %) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.
