This series add the possibility to select two of these signals on RTC pins : - LSCO (Low Speed Clock Output) that allow to output LSE clock on a pin. On STM32MP1x Discovery boards this feature is used to generate a clock to Wifi/Bluetooth module. - Alarm out that allow to send a pulse on a pin when alarm A of the RTC expires.
