+* Renesas R8A7740  Clock Pulse Generator (CPG)
+
+The CPG generates core clocks for the R8A7740 SoC. It includes three PLLs
+and several fixed ratio and variable ratio dividers.
+
+Required Properties:
+
+  - compatible: Must be "renesas,r8a7740-cpg-clocks"
+
+  - reg: Base address and length of the memory resource used by the CPG
+
+  - clocks: Reference to the two parent clocks
+  - #clock-cells: Must be 1
+  - clock-output-names: The names of the clocks. Supported clocks are
+    "system", "pllc0", "pllc1", "pllc2", "r", "usb24s", "i", "zg", "b",
+    "m1", "hp", "hpp", "usbp", "s", "zb", "m3", and "cp".
+
+  - renesas,mode: board-specific settings of the MD_CK* bits
+
+
+Example
