+
+description:
+  The System Reset Controller (SRC) generates the resets for the device. The
+  functional reset sources are programmable as either reset or interrupt. The
+  block also generates interrupts for various device events.
+
+properties:
+  compatible:
+    items:
+      - enum:
+          - fsl,vf610-src
+      - const: syscon
+
+  reg:
+    maxItems: 1
+
+  interrupts:
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+  - interrupts
+
+additionalProperties: false
+
+examples:
+  - |
+    #include <dt-bindings/interrupt-controller/irq.h>
+
+    reset@...6e000 {
+        compatible = "fsl,vf610-src", "syscon";
+        reg = <0x4006e000 0x1000>;
+        interrupts = <96 IRQ_TYPE_LEVEL_HIGH>;
