On STM32MP1x SOCs, RTC is able to output some signals on its own pins.
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.
Amelie Delaunay (2):
dt-bindings: rtc: stm32: add st,lsco optional property to select
output
rtc: stm32: add Low Speed Clock Output (LSCO) support
