description: |
  This module is used to create CCI DEVFREQ.
  The performance will depend on both CCI frequency and CPU frequency.
  For MT8183, CCI co-buck with Little core.
  Contain CCI opp table for voltage and frequency scaling.

properties:
  compatible:
    const: "mediatek,mt8183-cci"

  clocks:
