title: Renesas 9-series I2C PCIe clock generators

description: |
  The Renesas 9-series are I2C PCIe clock generators providing
  from 1 to 20 output clocks.

  When referencing the provided clock in the DT using phandle
  and clock specifier, the following mapping applies:

  - 9FGV0241:
    0 -- DIF0
    1 -- DIF1
  - 9FGV0441:
    0 -- DIF0
    1 -- DIF1
    2 -- DIF2
    3 -- DIF3
  - 9FGV0841:
    0 -- DIF0
    1 -- DIF1
    2 -- DIF2
    3 -- DIF3
    4 -- DIF4
    5 -- DIF5
    6 -- DIF6
    7 -- DIF7
