+Binding for the Synopsys HSDK reset controller
+
+This binding uses the common reset binding[1].
+
+[1] Documentation/devicetree/bindings/reset/reset.txt
+
+Required properties:
+- compatible: should be "snps,hsdk-reset".
+- reg: should always contain 2 pairs address - length: first for reset
+ configuration register and second for corresponding SW reset and status bits
+ register.
+- #reset-cells: from common reset binding; Should always be set to 1.
+
+Example:
+ reset: reset@880 {
+ compatible = "snps,hsdk-reset";
+ #reset-cells = <1>;
+ reg = <0x8A0 0x4>, <0xFF0 0x4>;
+ };
+
+Specifying reset lines connected to IP modules:
+ ethernet@.... {
+ ....
+ resets = <&reset HSDK_V1_ETH_RESET>;
+ ....
+ };
+
+The index could be found in <dt-bindings/reset/snps,hsdk-reset.h>
