jeromecoutant 1052993236 STM32 RTC : bypass shadow registers 
- RTC_SSR for the subseconds
- RTC_TR for the time
- RTC_DR for the date

These registers were accessed through shadow registers which are synchronized with PCLK1 (APB1 clock).
They are now accessed directly in order to avoid waiting for the synchronization duration.

jeromecoutant a816e93e9a STM32 LOWPOWERTIMER : introduce LPTIM feature 
STM32L0, L4, F7 and few F4 chip are supporting LPTIM feature.
We propose to allow user to use LPTIM for MBED LowPowerTimer API instead of using RTC wakeup timers.

By default, all targets that are supporting this feature have been configured.

STM32: RTC: Call irq_handler whenever interrupt fires
 2017-10-13 09:28:18 -05:00
Laurent MEUNIER e15ebd3c53 STM32: RTC: Call irq_handler whenever interrupt fires 
lp_ticker driver is the known registered user of RTC handler API.

In case, a lp_ticker is set in the past, the lp_ticker_fire_interrupt
will be called which itself sets the RTC interrupt as pending by calling
NVIC_SetPendingIRQ(RTC_WKUP_IRQn). This all happens without actual
programing of the RTC wake-up.

As a result the RTC HW and corresponding HAL layer doesn't expect an
interrupt to happen and will not call HAL_RTCEx_WakeUpTimerEventCallback.

To sove this situation, we will not use HAL_RTCEx_WakeUpTimerEventCallback
weak definition but rather call handler whenever an RTC interrupt fires.

Sam Grove 547320e99c Rename function st_rtc_localtime with _rtc_localtime 2017-06-07 23:24:48 -05:00
Vincent Coubard f880e44145 remove usage of mktime/localtime in favor of dedicated functions. 
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa.
In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.
