+Synopsys DesignWare Reset controller
+=======================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+
+- compatible: should be one of the following.
+ "snps,dw-high-reset" - for active high configuration
+ "snps,dw-low-reset" - for active low configuration
+
+- reg: physical base address of the controller and length of memory mapped
+ region.
+
+- #reset-cells: must be 1.
+
+example:
+
+ dw_rst_1: reset-controller@0000 {
+ compatible = "snps,dw-high-reset";
+ reg = <0x0000 0x4>;
+ #reset-cells = <1>;
+ };
+
+ dw_rst_2: reset-controller@1000 {i
+ compatible = "snps,dw-low-reset";
+ reg = <0x1000 0x8>;
+ #reset-cells = <1>;
+ };
