3* Renesas R8A7740 Clock Pulse Generator (CPG)
4
5The CPG generates core clocks for the R8A7740 SoC. It includes three PLLs
6and several fixed ratio and variable ratio dividers.
7
8Required Properties:
9
10 - compatible: Must be "renesas,r8a7740-cpg-clocks"
11
12 - reg: Base address and length of the memory resource used by the CPG
13
14 - clocks: Reference to the three parent clocks
15 - #clock-cells: Must be 1
16 - clock-output-names: The names of the clocks. Supported clocks are
17 "system", "pllc0", "pllc1", "pllc2", "r", "usb24s", "i", "zg", "b",
18 "m1", "hp", "hpp", "usbp", "s", "zb", "m3", and "cp".
19
20 - renesas,mode: board-specific settings of the MD_CK* bits
