* extcon: Redefine the unique id of supported external connectors without ↵Chanwoo Choi2015-06-131-1/+1
| | | | | | | | | | | | | | | 'enum extcon' type This patch just redefine the unique id of supported external connectors without 'enum extcon' type. Because unique id would be used on devictree file(*.dts) to indicate the specific external connectors like key number of input framework. So, I have the plan to move this definitions to following header file which includes the unique id of supported external connectors. - include/dt-bindings/extcon/extcon.h Fixes: 2a9de9c0f08d ("extcon: Use the unique id for external connector instead of string") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* extcon: Remove the optional name of extcon deviceChanwoo Choi2015-05-191-1/+0
| | | | | | | | | | | | | | | This patch removes the optional name of extcon device. Instead, extcon_dev_register() set the device name as 'extcon[number]' naming pattern. - /sys/class/extcon/[hardcoded device name] -> /sys/class/extcon/extcon[number] Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: MyungJoo Ham <myungjoo.ham@samsung.com> Cc: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Cc: Graeme Gregory <gg@slimlogic.co.uk> Cc: Kishon Vijay Abraham I <kishon@ti.com> Cc: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: Jaewon Kim <jaewon02.kim@samsung.com>

* extcon: adc-jack: Use devm_extcon_dev_register()Sangjung Woo2014-04-241-21/+9
| | | | | | | | | | Use the resource-managed extcon device register function (i.e. devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device is attached with this function, that extcon device is automatically unregistered on driver detach. That reduces tiresome managing code.

So, if extcon device has the parent device, it should set the pointer of parent device to edev.dev.parent in extcon device driver instead of in extcon_dev_register().

* Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds2012-10-021-1/+1

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...
