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
