+Hisilicon Platforms Device Tree Bindings
+----------------------------------------------------
+
+Hi4511 Board
+Required root node properties:
+ - compatible = "hisilicon,hi3620-hi4511";
+
+Hisilicon system controller
+
+Required properties:
+- compatible : "hisilicon,sysctrl"
+- reg : Register address and size
+
+Optional properties:
+- smp-offset : offset in sysctrl for notifying slave cpu booting
+ cpu 1, reg;
+ cpu 2, reg + 0x4;
+ cpu 3, reg + 0x8;
+ If reg value is not zero, cpun exit wfi and go
+- resume-offset : offset in sysctrl for notifying cpu0 when resume
+- reboot-offset : offset in sysctrl for system reboot
+
+Example:
+
+ /* for Hi3620 */
+ sysctrl: system-controller@fc802000 {
+ compatible = "hisilicon,sysctrl";
+ reg = <0xfc802000 0x1000>;
+ smp-offset = <0x31c>;
+ resume-offset = <0x308>;
+ reboot-offset = <0x4>;
+ };
