+
+description:
+  On Renesas RZ/V2H(P) SoCs, the CPG (Clock Pulse Generator) handles generation
+  and control of clock signals for the IP modules, generation and control of resets,
+  and control over booting, low power consumption and power supply domains.

+      - For CPG core clocks, the two clock specifier cells must be "CPG_CORE"
+        and a core clock reference, as defined in
+        <dt-bindings/clock/renesas,r9a09g057-cpg.h>,
+      - For module clocks, the two clock specifier cells must be "CPG_MOD" and
+        a module number.  The module number is calculated as the CLKON register
+        offset index multiplied by 16, plus the actual bit in the register
+        used to turn the CLK ON. For example, for CGC_GIC_0_GICCLK, the
+        calculation is (1 * 16 + 3) = 0x13.
