Thomas,
Here's a small collection of irqchip patches for 6.4. The only significant thing is the RISC-V IPI rework, which spans both the irqchip subsystem and the arch code (and is Acked by Palmer).
The rest is a bunch of errata workarounds, fixes and cleanups.
Please pull,
M.

Merge branch irq/misc-6.4 into irq/irqchip-next (2023-04-21 14:05:31 +0100)
---------------------------------------------------------------- irqchip changes for 6.4
- Large RISC-V IPI rework to make way for a new interrupt architecture
- More Loongarch fixes from Lianmin Lv, fixing issues in the so called "dual-bridge" systems.
- Workaround for the nvidia T241 chip that gets confused in 3 and 4 socket configurations, leading to the GIC malfunctionning in some contexts
- Drop support for non-firmware driven GIC configurarations now that the old ARM11MP Cavium board is gone
- Workaround for the Rockchip 3588 chip that doesn't correctly deal with the shareability attributes.
- Replace uses of of_find_property() with the more appropriate of_property_read_bool()
- Make bcm-6345-l1 request its MMIO region
- Add suspend support to the SiFive PLIC
- Drop support for stih415, stih416 and stid127 platforms
---------------------------------------------------------------- Alain Volmat (1): irqchip/st: Remove stih415/stih416 and stid127 platforms support
Anup Patel (7): RISC-V: Clear SIP bit only when using SBI IPI operations irqchip/riscv-intc: Allow drivers to directly discover INTC hwnode RISC-V: Treat IPIs as normal Linux IRQs RISC-V: Allow marking IPIs as suitable for remote FENCEs RISC-V: Use IPIs for remote TLB flush when possible RISC-V: Use IPIs for remote icache flush when possible irqchip/riscv-intc: Add empty irq_eoi() for chained irq handlers
Jianmin Lv (5): irqchip/loongson-eiointc: Fix returned value on parsing MADT irqchip/loongson-eiointc: Fix incorrect use of acpi_get_vec_parent irqchip/loongson-eiointc: Fix registration of syscore_ops irqchip/loongson-pch-pic: Fix registration of syscore_ops irqchip/loongson-pch-pic: Fix pch_pic_acpi_init calling

Mason Huo (1): irqchip/irq-sifive-plic: Add syscore callbacks for hibernation
Rob Herring (1): irqchip: Use of_property_read_bool() for boolean properties
Sebastian Reichel (1): irqchip/gic-v3: Add Rockchip 3588001 erratum workaround
Shanker Donthineni (1): irqchip/gicv3: Workaround for NVIDIA erratum T241-FABRIC-4
Álvaro Fernández Rojas (1): irqchip/bcm-6345-l1: Request memory region
