Merge tag 'irqchip-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip updates from Marc Zyngier:

 - A few new drivers for the Loongson MIPS platform (HTVEC, PIC, MSI)
 - A cleanup of the __irq_domain_add() API
 - A cleanup of the IRQ simulator to actually use some of
   the irq infrastructure
 - Some fixes for the Sifive PLIC when used in a multi-controller
   context
 - Fixes for the GICv3 ITS to spread interrupts according to the
   load of each CPU, and to honor managed interrupts
 - Numerous cleanups and documentation fixes
