+description: |
+  This interrupt controller is found in the Loongson-3 family of chips to transfer
+  interrupts from PCH connected on HyperTransport bus.
+
+properties:
+  compatible:
+    const: loongson,ls3-htintc
+
+  reg:
+    maxItems: 1
+
+  interrupts:
+    maxItems: 4
+    description: |
+      Four parent interrupts that recieve chained interrupt randomly.
+
+  interrupt-controller: true
+
+  '#interrupt-cells':
+    const: 1
+
+required:
+  - compatible
+  - reg
+  - interrupts
+  - interrupt-controller
+  - '#interrupt-cells'
+
+examples:
+  - |
+    #include <dt-bindings/interrupt-controller/irq.h>
+    htintc: interrupt-controller@fb000080 {
+      compatible = "loongson,ls3-htintc";
