Merge tag 'irqchip-fixes-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent

Pull irqchip fixes from Marc Zyngier:

 - Revert the wholesale conversion to platform drivers of the pdc, sysirq
   and cirq drivers, as it breaks a number of platforms even when the
   driver is built-in (probe ordering bites you).

 - Prevent interrupt from being lost with the STM32 exti driver

 - Fix wake-up interrupts for the MIPS Ingenic driver

 - Fix an embarassing typo in the new module helpers, leading to the probe
   failing most of the time

 - The promised TI firmware rework that couldn't make it into the merge
   window due to a very badly managed set of dependencies
