description: |
  HiSilicon 6421v600 should be connected inside a MIPI System Power Management
  (SPMI) bus. It provides interrupts and power supply.

  The GPIO and interrupt settings are represented as part of the top-level PMIC
  node.

  The SPMI controller part is provided by
  Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml
