Subject: [PATCH 0/6] rtc: stm32: add alarm out and LSCO features.
Date: Wed, 4 May 2022 15:02:27 +0200	[thread overview]
Message-ID: <20220504130233.330983-1-valentin.caron@foss.st.com> (raw)

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

Gabriel Fernandez (2):
  ARM: dts: stm32: add RTC LSCO support on stm32mp157c-dk2
  ARM: dts: stm32: add RTC LSCO support on stm32mp135f-dk
