description: |
  Renesas SoCs contain one or more memory controllers.  These memory
  controllers differ from one SoC variant to another, and are called by
  different names, e.g. "DDR Bus Controller (DBSC)", "DDR3 Bus State Controller
  (DBSC3)", or "SDRAM Bus State Controller (SBSC)").

  compatible:
    enum:
      - renesas,dbsc-r8a73a4  # R-Mobile APE6
      - renesas,dbsc3-r8a7740 # R-Mobile A1
      - renesas,sbsc-sh73a0   # SH-Mobile AG5

  interrupts:

  interrupt-names:
    items:
      - const: sec  # secure interrupt
      - const: temp # normal (temperature) interrupt

  power-domains:
    maxItems: 1
