Remove unnecessary low power ticker rescheduling

Russ Butler e69ecaab57 Don't reschedule ticker while dispatching
Wait until dispatching is finished before scheduling the next ticker
interrupt. This prevents unnecissary calls to set_interrupt from
periodic elements being added back.

This is particularly useful for the low power ticker on devices with
LPTICKER_DELAY_TICKS set to a non-zero value. This is because the low
power ticker cannot be reschduled immediately and needs to fall back
onto the microsecond ticker which temporarily locks deep sleep.

Update ticker to map closely to hardware
2017-10-13 09:18:02 -05:00
Russ Butler ec55b82acf Update ticker to map closely to hardware
Allow tickers to specify their native frequency and number of bits.
This allows the conversion to happen in common code rather than in
each vendor's implementation.

Martin Kojtal 10ea63b8e7 Ticker: add fire interrupt now function
fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.

set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.

It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.

The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)

All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.

Kevin Gilbert 7e2e80588d Removed bad \ref tag, but left in the tag name. Updated old param names in gpio_api.h and added new params in ticker_api.h 2017-06-08 15:52:31 -05:00
Vincent Coubard aeffd738c7 ticker_api: Code clarification
* update_interrupt renamed into schedule_interrupt
* update_current_timestamp renamed into update_present_time
* ticker_event_queue_t::timestamp renamed into
* ticker_event_queue_t::present_time
* Fix doxygen comments in ticker_api.h
* Update comments internal comments in mbed_ticker_api.c

Vincent Coubard 20149dfcf5 [HAL] Ad primitives for long lived timestamp to the ticker API.
- A new 64 timestamp type has been added: us_timestamp_t.
- Changed type of timestamp in ticker_events iinto us_timestamp_t.
- Event queue now have a to store a current, absolute timestamp.
- Add alternative versions of ticker_insert_event and ticker_read which accept
  in input us_timestamp_t.
- Add documentation explaining the limitation and behavior of ticker_read and
  ticker_insert_event.
