Input: add skeleton for simple polled devices input-polldev provides a skeleton for supporting simple input devices that need to be periodically scanned or polled to detect changes in their state. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Input: input-polldev - add module info This is required to load it as a module, as GPL-compatible license is necessary to use workqueues. Signed-off-by: Eric Piel <eric.piel@tremplin-utc.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Input: input-polldev - add sysfs interface for controlling poll interval 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.

Input: implement proper timer rounding for polled devices 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.

Input: polled device - do not start polling if interval is zero 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.
