STM32 LP timer that's available on STM32MP15x can wakeup the platform
using EXTI interrupts.

This series add:
- LP timer EXTI - GIC interrupt events to EXTI driver and device-tree
- LP timer wakeup-source to device-tree

Add all remaining LP timer exti direct events, e.g. for LP Timer 2 to 5.
LP timer 1 is already listed (e.g. exti 47).

LP timer can be used to wakeup from stop mode on stm32mp151.
Add wakeup-source properties to all LP timer instances.

Applied to irq/irqchip-next, thanks!

[1/3] irqchip/stm32-exti: Add all LP timer exti direct events support
      commit: a00e85b581fd5ee47e770b6b8d2038dbebbe81f9

Please route the last two patches via arm-soc.

Cheers,
