1*4882a593SmuzhiyunLantiq XWAY SoC RCU reset controller binding
2*4882a593Smuzhiyun============================================
3*4882a593Smuzhiyun
4*4882a593SmuzhiyunThis binding describes a reset-controller found on the RCU module on Lantiq
5*4882a593SmuzhiyunXWAY SoCs.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunThis node has to be a sub node of the Lantiq RCU block.

9*4882a593Smuzhiyun-------------------------------------------------------------------------------
10*4882a593SmuzhiyunRequired properties:
11*4882a593Smuzhiyun- compatible		: Should be one of
12*4882a593Smuzhiyun				"lantiq,danube-reset"
13*4882a593Smuzhiyun				"lantiq,xrx200-reset"
14*4882a593Smuzhiyun- reg			: Defines the following sets of registers in the parent
15*4882a593Smuzhiyun			  syscon device
16*4882a593Smuzhiyun			- Offset of the reset set register
17*4882a593Smuzhiyun			- Offset of the reset status register
18*4882a593Smuzhiyun- #reset-cells		: Specifies the number of cells needed to encode the
19*4882a593Smuzhiyun			  reset line, should be 2.
20*4882a593Smuzhiyun			  The first cell takes the reset set bit and the
21*4882a593Smuzhiyun			  second cell takes the status bit.

24*4882a593SmuzhiyunExample for the reset-controllers on the xRX200 SoCs:
25*4882a593Smuzhiyun	reset0: reset-controller@10 {
26*4882a593Smuzhiyun		compatible = "lantiq,xrx200-reset";
27*4882a593Smuzhiyun		reg <0x10 0x04>, <0x14 0x04>;
28*4882a593Smuzhiyun
29*4882a593Smuzhiyun		#reset-cells = <2>;
30*4882a593Smuzhiyun	};
