+title: Renesas RZ/{G2L,V2L,V2M} Clock Pulse Generator / Module Standby Mode
+
+maintainers:
+ - Geert Uytterhoeven <geert+renesas@glider.be>
+
+description: |
+ On Renesas RZ/{G2L,V2L}-alike SoC's, the CPG (Clock Pulse Generator) and Module
+ Standby Mode share the same register block. On RZ/V2M, the functionality is
+ similar, but does not have Clock Monitor Registers.
+
+ They provide the following functionalities:
+ - The CPG block generates various core clocks,
+ - The Module Standby Mode block provides two functions:
+ 1. Module Standby, providing a Clock Domain to control the clock supply
+ to individual SoC devices,
+ 2. Reset Control, to perform a software reset of individual SoC devices.
+
