Johan Lafon	a63bb6317c	drivers: rtc: stm32: allow new RTC driver to work with BBRAM STM32 BBRAM depends on RTC to work. This changes STM32 RTC init stage to PRE_KERNEL_1 to allow RTC driver to initialize before BBRAM driver. Some adjustments are made so that kernel API is not used during the init procedure.

Johan Lafon	e46aff5902	drivers: rtc: stm32: avoid using LL_RTC_Init LL_RTC_Init() internally uses LL_RTC_EnterInitMode() wich uses a blocking while loop. This rewrite uses the less CPU time wasteful local rtc_stm32_enter_initialization_mode() instead. As a side effect LL_RTC_InitTypeDef in rtc_stm32_config is not needed anymore.

Erwan Gouriou	00a9cb81c0	drivers: rtc: stm32: Exclude STM32F1 from current RTC driver STM32F1 series RTC is not compatible with other STM32F1 series, and it uses a different LL API. Current implementation of the driver doesn't take this into account, so we need to explicitly exclude STM32F1 series support until some changes are made.

Kim Bøndergaard	b3c46083fb	drivers: rtc: stm32: New stm32 RTC driver STM32 RTC driver for the new RTC API. Can't coexist with old COUNTER based RTC Though supported by HW, RTC_ALARM still to be supported by driver Signed-off-by: Kim Bøndergaard <kim.bondergaard@prevas.dk>	2 years ago
