-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@1c202c0 {
-	#reset-cells = <1>;
-	compatible = "allwinner,sun6i-a31-ahb1-reset";
-	reg = <0x01c202c0 0xc>;
-};
