Merge branch irq/misc-6.1 into irq/irqchip-next

* irq/misc-6.1:
  : .
  : Misc irqchip updates for 6.1:
  :
  : - Allow generic irqchip support without selecting CONFIG_OF_IRQ
  :
  : - Fix a couple of bindings for TI interrupts controllers
  :
  : - Yet another binding update for a Renesas SoC
  :
  : - The obligatory fixes from the spelling police
  : .
  dt-bindings: irqchip: renesas,irqc: Add r8a779g0 support
  irqchip/gic-v3: Fix typo in comment
  dt-bindings: interrupt-controller: ti,sci-intr: Fix missing reg property in the binding
  dt-bindings: irqchip: ti,sci-inta: Fix warning for missing #interrupt-cells
  irqchip: Make irqchip_init() usable on pure ACPI systems
