+title: Renesas SH7750/7751 Clock Pulse Generator (CPG)
+
+maintainers:
+  - Yoshinori Sato <[e-mail]>
+
+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.
