+* Hisilicon Hi3559A Clock Controller
+
+The Hi3559A clock controller generates and supplies clock to various
+controllers within the Hi3559A SoC.
+
+Required Properties:
+
+- compatible: the compatible should be one of the following strings to
+ indicate the clock controller functionality.
+
+ - "hisilicon,hi3559av100-clock"
+
+- 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/hi3559av100-clock.h>.
+
+Examples:
+
+ clock: clock0 {
+ compatible = "hisilicon,hi3559av100-clock", "syscon";
+ #clock-cells = <1>;
+ #reset-cells = <2>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ reg = <0x0 0x12010000 0x0 0x10000>;
+ };
+
+ uart0: uart@12100000 {
+ compatible = "arm,pl011", "arm,primecell";
+ reg = <0x12100000 0x1000>;
+ interrupts = <0 6 4>;
+ clocks = <&clock HI3559AV100_UART0_CLK>;
+ clock-names = "apb_pclk";
+ };
