Merge tag 'irq-core-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "Core:

   - Make affinity changes take effect immediately for interrupt
     threads. This reduces the impact on isolated CPUs as it pulls over
     the thread right away instead of doing it after the next hardware
     interrupt arrived.

   - Cleanup and improvements for the interrupt chip simulator

   - Deduplication of the interrupt descriptor initialization code so
     the sparse and non-sparse mode share more code.

  Drivers:

   - A set of conversions to platform_drivers::remove_new() which gets
     rid of the pointless return value.

   - A new driver for the Starfive JH8100 SoC

   - Support for Amlogic-T7 SoCs

   - Improvement for the interrupt handling and EOI management for the
     loongson interrupt controller.

   - The usual fixes and improvements all over the place"

+title: StarFive External Interrupt Controller
+
+description:
+  StarFive SoC JH8100 contain a external interrupt controller. It can be used
+  to handle high-level input interrupt signals. It also send the output
+  interrupt signal to RISC-V PLIC.
