+Allwinner sunxi Peripheral 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:
+ "allwinner,sun6i-a31-ahb1-reset"
+ "allwinner,sun6i-a31-clock-reset"
+- reg: should be register base and length as documented in the
+ datasheet
+- #reset-cells: 1, see below
+
+example:
+
+ahb1_rst: reset@01c202c0 {
+ #reset-cells = <1>;
+ compatible = "allwinner,sun6i-a31-ahb1-reset";
+ reg = <0x01c202c0 0xc>;
+};
