      7title: Binding for Renesas 9-series I2C PCIe clock generators
      8
      9description: |
     10  The Renesas 9-series are I2C PCIe clock generators providing
     11  from 1 to 20 output clocks.
     12
     13  When referencing the provided clock in the DT using phandle
     14  and clock specifier, the following mapping applies:
     15
     16  - 9FGV0241:
     17    0 -- DIF0
     18    1 -- DIF1
