Merge tag 'irqchip-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Pull irqchip changes from Marc Zyngier:

 - 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
