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 .../interrupt-controller/st,stm32-exti.txt | 4 + arch/arm/boot/dts/stm32mp157c.dtsi | 1 + drivers/irqchip/irq-stm32-exti.c | 116 ++++++++++++++++++--- 3 files changed, 105 insertions(+), 16 deletions(-) -- 2.15.0
