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/spmi/hisilicon,hisi-spmi-controller.yaml
