+Lantiq XWAY SoC RCU reset controller binding
+============================================
+
+This binding describes a reset-controller found on the RCU module on Lantiq
+XWAY SoCs.
+
+This node has to be a sub node of the Lantiq RCU block.
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible : Should be one of
+ "lantiq,danube-reset"
+ "lantiq,xrx200-reset"
+- reg : Defines the following sets of registers in the parent
+ syscon device
+ - Offset of the reset set register
+ - Offset of the reset status register
+- #reset-cells : Specifies the number of cells needed to encode the
+ reset line, should be 2.
+ The first cell takes the reset set bit and the
+ second cell takes the status bit.
+
+-------------------------------------------------------------------------------
+Example for the reset-controllers on the xRX200 SoCs:
+ reset0: reset-controller@10 {
+ compatible = "lantiq,xrx200-reset";
+ reg <0x10 0x04>, <0x14 0x04>;
+
+ #reset-cells = <2>;
+ };
