title: Renesas RZ/V2H(P) Clock Pulse Generator (CPG)

maintainers:
  - Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

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.

  '#clock-cells':
    description: |
      - 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.

    description:
      The single reset specifier cell must be the reset number. The reset number
      is calculated as the reset register offset index multiplied by 16, plus the
      actual bit in the register used to reset the specific IP block. For example,
      for SYS_0_PRESETN, the calculation is (3 * 16 + 0) = 0x30.
