Merge tag 'irq-core-2024-07-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 

Pull interrupt subsystem updates from Thomas Gleixner:
 "Core:

   - Provide a new mechanism to create interrupt domains. The existing
     interfaces have already too many parameters and it's a pain to
     expand any of this for new required functionality.

     The new function takes a pointer to a data structure as argument.
     The data structure combines all existing parameters and allows for
     easy extension.

     The first extension for this is to handle the instantiation of
     generic interrupt chips at the core level and to allow drivers to
     provide extra init/exit callbacks.

     This is necessary to do the full interrupt chip initialization
     before the new domain is published, so that concurrent usage sites
     won't see a half initialized interrupt domain. Similar problems
     exist on teardown.

     This has turned out to be a real problem due to the deferred and
     parallel probing which was added in recent years.

     Handling this at the core level allows to remove quite some accrued
     boilerplate code in existing drivers and avoids horrible
     workarounds at the driver level.

   - The usual small improvements all over the place

  Drivers:

   - Add support for LAN966x OIC and RZ/Five SoC

   - Split the STM ExtI driver into a microcontroller and a SMP version
     to allow building the latter as a module for multi-platform
     kernels

   - Enable MSI support for Armada 370XP on platforms which do not
     support IPIs

   - The usual small fixes and enhancements all over the place"

description: |

  The Microchip LAN966x outband interrupt controller (OIC) maps the internal

  interrupt sources of the LAN966x device to an external interrupt.

  When the LAN966x device is used as a PCI device, the external interrupt is

  routed to the PCI interrupt.
