Merge tag 'irqchip-fixes-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgentirq-urgent-2020-08-30
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
