-Binding for Qualcomm Atheros AR7xxx/AR9XXX reset controller
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.

-Required Properties:
-- compatible: has to be "qca,<soctype>-reset", "qca,ar7100-reset"
-              as fallback
-- reg: Base address and size of the controllers memory area
-- #reset-cells : Specifies the number of cells needed to encode reset
-                 line, should be 1
-
-Example:
-
-	reset-controller@...6001c {
-		compatible = "qca,ar9132-reset", "qca,ar7100-reset";
-		reg = <0x1806001c 0x4>;
-
-		#reset-cells = <1>;
