-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>;
-	};
