Wolfram Sanga6659622014-03-07 17:00:37 +01001* Renesas RZ Clock Pulse Generator (CPG)
2
3The CPG generates core clocks for the RZ SoCs. It includes the PLL, variable
4CPU and GPU clocks, and several fixed ratio dividers.
5
6Required Properties:
7
8 - compatible: Must be one of
9 - "renesas,r7s72100-cpg-clocks" for the r7s72100 CPG
10 - "renesas,rz-cpg-clocks" for the generic RZ CPG
11 - reg: Base address and length of the memory resource used by the CPG
12 - clocks: References to possible parent clocks. Order must match clock modes
13 in the datasheet. For the r7s72100, this is extal, usb_x1.
14 - #clock-cells: Must be 1
15 - clock-output-names: The names of the clocks. Supported clocks are "pll",
16 "i", and "g"
