HID: wiimote: remove old static extension support

2013-06-03T09:07:05+00:00

We now have dynamic hotplug support so the old static extensions are no longer needed nor used. Remove it along CONFIG_HID_WIIMOTE_EXT. Signed-off-by: David Herrmann Signed-off-by: Jiri Kosina

HID: wiimote: keep HID device open

2013-06-03T09:06:59+00:00

We need constant I/O to keep the state up-to-date and not miss any packets. Hence, call hid_hw_open() during setup and hid_hw_close() during destruction. These are no-ops for Bluetooth HIDP, but lets be safe. Signed-off-by: David Herrmann Signed-off-by: Jiri Kosina

HID: wiimote: extend driver description

2013-06-03T09:06:58+00:00

The hid-wiimote driver supports more than the Wii Remote. Nintendo produced many devices based on the Wii Remote, which have extension devices built-in. It is not clear to many users, that these devices have anything in common with the Wii Remote, so fix the driver description. This also updates the copyright information for the coming hotplugging rework. Signed-off-by: David Herrmann Signed-off-by: Jiri Kosina

HID: wiimote: fix nunchuck button parser

2013-02-18T09:41:52+00:00

The buttons of the Wii Remote Nunchuck extension are actually active low. Fix the parser to forward the inverted values. The comment in the function always said "0 == pressed" but the implementation was wrong from the beginning.

Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq

2012-10-02T16:54:49+00:00

Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. 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() ...

HID: wiimote: Parse calibration data of balance boards

2012-09-17T15:22:43+00:00

The raw pressure-data that is reported by balance-boards is pretty useless unless calibration data is applied. Therefore, we read the full calibration data on extension initialization and apply it to every reported data. Signed-off-by: David Herrmann Signed-off-by: Florian Echtler Signed-off-by: Jiri Kosina

HID: wiimote: Add Nintendo Balance-Board support

2012-09-17T15:19:49+00:00

The Nintendo Balance-Board is a controller which behaves exactly like the Wii Remote but reports all its data through a special extension device. Hence, we can simply add the Balance-Board as extension device and we get full support for it. Tested-by: Florian Echtler Signed-off-by: David Herrmann Signed-off-by: Jiri Kosina

workqueue: deprecate system_nrt[_freezable]_wq

2012-08-20T21:51:24+00:00

system_nrt[_freezable]_wq are now spurious. Mark them deprecated and convert all users to system[_freezable]_wq. If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant, so there's no reason to use system_nrt[_freezable]_wq. Please use system[_freezable]_wq instead. This patch doesn't make any functional difference. Signed-off-by: Tejun Heo Acked-By: Lai Jiangshan Cc: Jens Axboe Cc: David Airlie Cc: Jiri Kosina Cc: "David S.
