Linus,

please pull the latest irq/core branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-core-2023-08-28

up to: 02362c9a99b6: Merge tag 'irqchip-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Boring updates for the interrupt subsystem:

Core:

- Prevent a deadlock of nested interrupt threads vs.
synchronize_hard()

- Removal of a stale extern declaration

Drivers:

- The first new driver since v6.2 for Amlogic-C3 SoCs

- The usual small fixes, cleanups and improvements all over
the place

Thanks,

tglx
