+title: RDA Micro Modem Reset
+
+maintainers:
+  - Dang Huynh <dang.huynh@...nlining.org>
+
+description:
+  The modem has a reset register that can be used to fully reset the board.
+
+  To do that, a magic value needs to be written to unprotect the register,
+  then the soft reset register can be used.
+
+properties:
+  compatible:
+    const: rda,md-reset
+
+  reg:
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+
+additionalProperties: false
+
+examples:
+  - |
+    reset-controller@...0000 {
+      compatible = "rda,md-reset";
+      reg = <0x1a00000 0x4>;
+    };
