title: HiSilicon 6421v600 SPMI PMIC

maintainers:

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
  drivers/staging/hikey9xx/hisilicon,hisi-spmi-controller.yaml.

properties:
  $nodename:
    pattern: "pmic@[0-9a-f]"

  compatible:
    const: hisilicon,hi6421v600-spmi

  reg:
    maxItems: 1

  '#interrupt-cells':

  interrupt-controller:
    description:
      Identify that the PMIC is capable of behaving as an interrupt controller.
