+description: |
+  On Renesas RZ/G2L SoC, the CPG (Clock Pulse Generator) and MSTP
+  (Module Stop and Software Reset) share the same register block.
+
+  They provide the following functionalities:
+    - The CPG block generates various core clocks,
+    - The MSTP block provides two functions:
+        1. Module Stop, 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.

renesas,r9a07g044-cpg?

As some IP blocks present in RZ/G2L aren't present in RZ/G2LC clock
handling will differ so as a result SoC specific compatible string is
added.

The RZ/G2L Hardware User's Manual Rev. 0.41 doesn't mention any
differences between the CPG on RZ/G2L and RZ/G2LC.  So I think it's
safe to have a single driver for both members.

Gr{oetje,eeting}s,
