Merge tag 'irqchip-fixes-5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier:
- A couple of fixes after the IPI as IRQ patches (Kconfig, bcm2836)
- Two SiFive PLIC fixes (irq_set_affinity, hierarchy handling)
- "unmapped events" handling for the ti-sci-inta controller
- Tidying up for the irq-mst driver (static functions, Kconfig)
- Small cleanup in the Renesas irqpin driver
- STM32 exti can now handle LP timer events
