+Hisilicon HiP01 system controller
+
+Required properties:
+- compatible : "hisilicon,hip01-sysctrl"
+- reg : Register address and size
+
+The HiP01 system controller is mostly compatible with hisilicon
+system controller,but it has some specific control registers for
+HIP01 SoC family, such as slave core boot, and also some same
+registers located at different offset.
+
+Example:
+
+       /* for hip01-ca9x2 */
+       sysctrl: system-controller@10000000 {
+               compatible = "hisilicon,hip01-sysctrl", "hisilicon,sysctrl";
