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>;

	};
