* irq/loongarch-fixes-6.5:
  : .
  : Yet another series of random fixes for the Loongson/Loongarch
  : string of interrupt controller, covering
  :
  : - affinity setting,
  : - trigger polarity,
  : - wake-up,
  : - DT support
  : .
  irqchip/loongson-eiointc: Add DT init support
  dt-bindings: interrupt-controller: Add Loongson EIOINTC
  irqchip/loongson-eiointc: Fix irq affinity setting during resume
  irqchip/loongson-liointc: Add IRQCHIP_SKIP_SET_WAKE flag
  irqchip/loongson-liointc: Fix IRQ trigger polarity
  irqchip/loongson-pch-pic: Fix potential incorrect hwirq assignment
  irqchip/loongson-pch-pic: Fix initialization of HT vector register

+
+description: |
+  This interrupt controller is found on the Loongson-3 family chips and
+  Loongson-2K series chips and is used to distribute interrupts directly to
+  individual cores without forwarding them through the HT's interrupt line.
