* power: supply: ab8500: Use dev_err_probe() for IIO channelsLinus Walleij2020-12-121-4/+3
| | | | | | | | | | | | | The code obtaining the ADC channels is outdated: it is trying to work around the IIO subsystem not returning the right -EPROBE_DEFER error code. Fix this up by using the dev_err_probe() helper so we defer silently where appropriate and not bail out if the IIO core returns -EPROBE_DEFER as happens now.

* power: supply: ab8500_fg: Request all IRQs as threadedLinus Walleij2020-12-121-36/+11
| | | | | | | | | | | | | | | | | | | | | | Since these IRQs are cascaded from a nested IRQ, the generic IRQ system detects this and refuse to deliver a fastpath IRQ in response to request_irq(): nested = irq_settings_is_nested_thread(desc); if (nested) { if (!new->thread_fn) { ret = -EINVAL; goto out_mput; } (...) Threaded IRQs work just as well so let's just request threaded IRQs. One of the IRQs are alread requested as threaded anyways.

* power: supply: ab8500: Convert to dev_pm_opsLinus Walleij2020-12-121-12/+7
| | | | | | | | | | Switch over to using generic dev_pm_ops since these drivers aren't even using the special power state passed to the legacy call.

| | | | | | | | | | | | Use a local "dev" helper variable to make the probe() code easier to read in the ab8500 subdrivers. Drop out-of-memory messages as these should come from the slab core.

* power: supply: ab8500: stop using getnstimeofday64()Arnd Bergmann2018-07-061-8/+6
| | | | | | | | | | | | | | | | getnstimeofday64() is deprecated in favor of the ktime_get() family. The direct replacement would be ktime_get_real_ts64(), but we only need the seconds value, and it seems better to use boottime than real time to avoid unexpected behavior with a concurrent settimeofday(). ktime_get_seconds() might also work, but it seems better to use boottime than monotonic time since I assume that the charging process continues during suspend.

| | | | | | | | | | | | | The AB8540 was an evolved version of the AB8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the AB8500.

* power: ab8500_fg: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2016-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces deprecated create_singlethread_workqueue(). This is the identity conversion. 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. Hence, a dedicated ordered workqueue has been used here. The WQ_MEM_RECLAIM flag has been set to guarantee forward progress under memory pressure.
