[PATCH 0/9] ARM: dts: st: add WLAN/BT on disco boards

[Valentin Caron]

This series enable WLAN/BT module on stm32mp1x discovery boards.
Use LSCO from RTC to supply 32kHz clock to WLAN/BT modules.
This is done by selecting "rtc_lsco_pins_a" in the WLAN pinctrl node.

And also add RTC nodes on stm32mp25x to enable RTC on stm32mp257f-ev1
board.

I applied the series by removing patch[9] as it raised a build issue.
Furthermore, the pin pin configuration in patch [9] was not used in a 
board, so no need to take it.
