[PATCH v2 0/2] Make STM32 interrupt controller use hwspinlock

[Benjamin Gaignard]

From: Benjamin Gaignard <benjamin.gaignard@xxxxxx>

This series allow to protect STM32 interrupt controller configuration registers
with a hwspinlock to avoid conflicting accesses between processors. 

version 2:
- rework hwspinlock locking sequence in stm32 irqchip to take care of the
  cases where hwspinlock node is disabled or not yet probed

Benjamin Gaignard (2):
  irqchip: stm32: protect configuration registers with hwspinlock
  ARM: dts: stm32: Add hwlock for irqchip on stm32mp157
