* 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 three 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
|
|
|
|
|
|
