+* Hisilicon Hi3620 Clock Controller
+
+The Hi3620 clock controller generates and supplies clock to various
+controllers within the Hi3620 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+  - "hisilicon,hi3620-clock" - controller compatible with Hi3620 SoC.
+  - "hisilicon,hi3620-mmc-clock" - controller specific for Hi3620 mmc.
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.
+
+All these identifier could be found in <dt-bindings/clock/hi3620-clock.h>.
