Linus,

please pull the latest irq/urgent branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-2022-06-19

up to: 6872fcac7158: Merge tag 'irqchip-fixes-5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent


A set of interrupt subsystem updates:

Core:
- Ensure runtime power management for chained interrupts

Drivers:
- A collection of OF node refcount fixes

- Unbreak MIPS uniprocessor builds

- Fix xilinx interrupt controller Kconfig dependencies

- Add a missing compatible string to the Uniphier driver

Thanks,

tglx
