Linus Torvalds 93287e28bc Updates for the interrupt subsystem:

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
