+Axxia Restart Driver
+
+This driver can do reset of the Axxia SoC. It uses the registers in the syscon
+block to initiate a chip reset.
+
+Required Properties:
+ -compatible: "lsi,axm55xx-reset"
+ -syscon: phandle to the syscon node.
+
+Example:
+
+ syscon: syscon@2010030000 {
+ compatible = "lsi,axxia-syscon", "syscon";
+ reg = <0x20 0x10030000 0 0x2000>;
+ };
+
+ reset: reset@2010031000 {
+ compatible = "lsi,axm55xx-reset";
+ syscon = <&syscon>;
+ };
