+Bitmain BM1880 SoC Reset Controller
+===================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required properties:
+- compatible: Should be "bitmain,bm1880-reset"
+- reg: Offset and length of reset controller space in SCTRL.
+- #reset-cells: Must be 1.
+
+Example:
+
+ rst: reset-controller@c00 {
+ compatible = "bitmain,bm1880-reset";
+ reg = <0xc00 0x8>;
+ #reset-cells = <1>;
+ };
