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

version 3:
- with bindings patch

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 (3):
dt-bindings: interrupt-controller: stm32: Document hwlock properties
irqchip: stm32: protect configuration registers with hwspinlock
ARM: dts: stm32: Add hwlock for irqchip on stm32mp157
