2009-12-07Input: add generic support for sparse keymapsDmitry Torokhov
More and more devices choose to reimplement support for sparse keymaps first introduced by wistron driver. Move it into a library module so it can be easily used by interested parties. Reviewed-by: Anisse Astier <anisse@astier.eu> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-11-23Input: polled device - do not start polling if interval is zeroSamu Onkalo
If the poll interval is set to 0 via new sysfs entry and device is opened after that, polling is started with interval 0. This causes huge CPU load. Same happens if the rate was 0 when the device was closed and then reopened. Signed-off-by: Samu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-11-23Input: polled device - schedule first poll immediatelyDmitry Torokhov
It does not make sense to wait poll_interval before performing first read after opening the device, schedule the read immediately instead. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-11-20Input: input-polldev - add sysfs interface for controlling poll intervalSamu Onkalo
Sysfs entry for reading and setting of the polling interval. If the interval is set to 0, polling is stopped. Polling is restarted when interval is changed to non-zero. sysfs entries: poll = current polling interval in msec (RW) max = max allowed polling interval (RO) min = min allowed polling interval (RO) Minimum and maximum limit for interval can be set while setting up the device. Interval can be adjusted even if the input device is not currently open.

2009-10-18Input: add open and close methods for polled devicesSamu Onkalo
Optional open and close methods for preparing and closing the device. Signed-off-by: Samu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-04-02Input: remove private member from input_dev structureDmitry Torokhov
Everyone should be using input_{get|set}_drvdata() by now. Alias them to dev_{get|set}_drvdata() and remove ->private. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-01-21Input: implement proper timer rounding for polled devicesStephen Hemminger
Rounding doesn't matter for the first tick, but we want succeeding ticks to be aligned on second boundary if poll interval is large enough. Also: cancel_rearming_delayed_workqueue is marked as obsolete in workqueue.h so use cancel_delayed_work_sync.

2007-09-26Input: polled device power savingStephen Hemminger
For slow running polling, it saves power to align wakeups on tick boundary. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2007-06-13Input: move input-polldev to drivers/inputDmitry Torokhov
To work around deficiences in Kconfig that allows to "select" a symbol without automatically selecting all dependencies for that symbol move input-polldev from drivers/input/misc to drivers/input thus removing extra dependency on CONFIG_INPUT_MISC. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
