Merge tag 'irqchip-fixes-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip/genirq fixes from Marc Zyngier:
- Invoke runtime PM for chained interrupts, aligning the behaviour
with that of 'normal' interrupts
- A flurry of of_node refcounting fixes
- A fix for the recently merged loongarch that broke UP MIPS
- A configuration fix for the Xilinx interrupt controller
- Yet another new compat string for the Uniphier interrupt controller
