5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*. 
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

f7697ff393 stmhal: Add rtc.init() method to force RTC to re-initialise. 2015-12-04 12:05:05 +00:00

86aa16bea6 stmhal: Implement delayed RTC initialization with LSI fallback. 
If RTC is already running at boot then it's left alone.  Otherwise, RTC is
started at boot but startup function returns straight away.  RTC startup
is then finished the first time it is used.  Fallback to LSI if LSE fails
to start in a certain time.

Also included:
 MICROPY_HW_CLK_LAST_FREQ
        hold pyb.freq() parameters in RTC backup reg
 MICROPY_HW_RTC_USE_US
        option to present datetime sub-seconds in microseconds
 MICROPY_HW_RTC_USE_CALOUT
        option to enable RTC calibration output

CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

8f7ff854b0 stmhal/rtc: LSx oscillator is only initialized upon initial power up. 
Initial power up also includes VBAT.

If LSE is configured but fails to start, LSI is used until next full power
cycle.  Also handles STM32F7xx variant.

3819634469 stmhal: Make RTC init skip startup if LTE is already enabled and ready. 
This prevents the loss of RTC time when exiting from standby mode, since
the RTC is paused while it is being re-inited and this loses about 120ms.

Thanks to @chuckbook for the patch.

49fe6dc89a stmhal: Add config option to use LSE/LSI for RTC. 
Most boards (except the pyboard) don't have a 32kHz crystal so they
should use the LSI for the RTC.

dac79324b5 stmhal: Add rtc.wakeup method, to set wakeup timer. 
This allows to wake from low-power modes at a regular interval.

This method is preliminary, pending testing and API overhaul.

57c70d6073 stmhal: Move RTC HAL init functions to rtc.c, where they belong. 
So can remove unnecessary stm32f4xx_hal_msp.c file.

ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int. 
Addressing issue #50, still some way to go yet.

04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
