+Realtek RTD129x Reset Controller
+================================
+
+Required properties:
+- compatible : Should be "realtek,rtd1295-reset"
+- reg : Should contain the register address and 4 as size.
+- #reset-cells : Should be 1
+
+See reset.txt for common reset controller bindings.
+
+
+Example:
+
+ reset-controller@98000000 {
+ compatible = "realtek,rtd1295-reset";
+ reg = <0x98000000 0x4>;
+ #reset-cells = <1>;
