Merge tag 'irqchip-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip/genirq updates from Marc Zyngier:

 * Core code update:

  - Non-SMP IRQ affinity fixes, allowing UP kernel to behave similarly
    to SMP ones for the purpose of interrupt affinity

  - Let irq_set_chip_handler_name_locked() take a const struct irq_chip *

  - Tidy-up the NOMAP irqdomain API variant

  - Teach action_show() to use for_each_action_of_desc()

  - Make irq_chip_request_resources_parent() allow the parent callback
    to be optional

  - Remove dynamic allocations from populate_parent_alloc_arg()

 * New drivers:

  - Merge the long awaited IRQ support for the LoongArch architecture,
    with the provisional ACPICA update (to be reverted once the official
    support lands)

  - New Renesas RZ/G2L IRQC driver, equipped with its companion GPIO
    driver

 * Driver updates

  - Optimise the hot path operations for the SiFive PLIC, trading the
    locking for per-CPU priority masking masking operations which are
    apparently faster

  - Work around broken PLIC implementations that deal pretty badly with
    edge-triggered interrupts. Flag two implementations as affected.

  - Simplify the irq-stm32-exti driver, particularly the table that
    remaps the interrupts from exti to the GIC, reducing the memory usage

  - Convert the ocelot irq_chip to being immutable

  - Check ioremap() return value in the MIPS GIC driver

  - Move MMP driver init function declarations into the common .h

  - The obligatory typo fixes
