+Hisilicon System Reset Controller
+======================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+The reset controller node must be a sub-node of the chip controller
+node on SoCs.
+
+Required properties:
+- compatible: may be "hisilicon,hi6220-reset-ctl"
+- reg: should be register base and length as documented in the
+  datasheet
+- #reset-cells: 1, see below
+
+Example:
+
+reset_ctrl: reset_ctrl@f7030000 {
+compatible = "hisilicon,hi6220-reset-ctl";
+reg = <0x0 0xf7030000 0x0 0x1000>;
+#reset-cells = <1>;
+};
+
+Specifying reset lines connected to IP modules
+==============================================
+example:
+
+        uart1: uart1@..... {
+                ...
+                resets = <&reset_ctrl 0x305>;
+                ...
+        };
