Merge tag 'irq-core-2022-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt updates from Thomas Gleixner:
"Core code:
- Provide a generic wrapper which can be utilized in drivers to
handle the problem of force threaded demultiplex interrupts on RT
enabled kernels. This avoids conditionals and horrible quirks in
drivers all over the place
- Fix up affected pinctrl and GPIO drivers to make them cleanly RT
safe
Interrupt drivers:
- A new driver for the FSL MU platform specific MSI implementation
- Make irqchip_init() available for pure ACPI based systems
- Provide a functional DT binding for the Realtek RTL interrupt chip
- The usual DT updates and small code improvements all over the
place"
