+title: Renesas SH7750/7751 Clock Pulse Generator (CPG)
+
+maintainers:
+ - Yoshinori Sato <ysato@users.sourceforge.jp>
+
+description:
+ The Clock Pulse Generator (CPG) generates core clocks for the SoC. It
+ includes PLLs, and variable ratio dividers.
+
+ The CPG may also provide a Clock Domain for SoC devices, in combination with
+ the CPG Module Stop (MSTP) Clocks.
