Subject: [GIT pull] irq/urgent for 5.19-rc3
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
