+===========================================================
+
+Required properties:
+    - compatible: shall contain "fsl,ls1028a-plldig"
+    - reg: Physical base address and size of the block registers
+    - #clock-cells: shall contain 1.
+    - clocks: a phandle + clock-specifier pairs, here should be
+    specify the reference clock of the system
+
+
+Example:
+
+/ {
+        ...
+
+        dpclk: clock-controller@f1f0000 {
+                compatible = "fsl,ls1028a-plldig";
+                reg = <0x0 0xf1f0000 0x0 0xffff>;
+                #clock-cells = <1>;
+                clocks = <&osc_27m>;
+        };
