[PATCH] ARM: dts: stm32: use exti 19 as main interrupt to support RTC wakeup on stm32mp157

[Marek Vasut]

From: Alexandre Torgue <alexandre.torgue at st.com>

Link between GIC and exti line is now done inside EXTI driver. So in order
to be wake up source exti irqchip has to be used.

This comes from ST github repo, v5.4-stm32mp [93a67bfcf197ffad8d8962369b56b8b714d1447e]
It would be good to include this, because indeed, this makes rtcwake -s 5 -m mem work.
