Merge tag 'irq-core-2022-03-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt updates from Thomas Gleixner:
"Core code:
- Provide generic_handle_irq_safe() which can be invoked from any
context (hard interrupt or threaded). This allows to remove ugly
workarounds in drivers all over the place.
- Use generic_handle_irq_safe() in the affected drivers.
- The usual cleanups and improvements.
Interrupt chip drivers:
- Support for new interrupt chips or not yet supported variants:
STM32MP14, Meson GPIO, Apple M1 PMU, Apple M1 AICv2, Qualcomm MPM
- Convert the Xilinx driver to generic interrupt domains
- Cleanup the irq_chip::name handling
- The usual cleanups and improvements all over the place"
