[PATCH v3 0/3] Make STM32 interrupt controller use hwspinlock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
