+title: Realtek DHC SoCs Interrupt Controller Device Tree Bindings
+
+description:
+  This interrupt controller is a component of Realtek DHC SoCs and
+  is designed to receive interrupts from peripheral devices.
+
+  Each DHC SoC has two sets of interrupt controllers, each capable of
+  handling up to 32 interrupts.
