description: |
  The Power On device for Qualcomm PM8xxx is MFD supporting pwrkey
  and resin along with the Android reboot-mode.

  This DT node has pwrkey and resin as sub nodes.

  reg:
    description: |
      Specifies the SPMI base address for the PON (power-on) peripheral.  For
      PMICs that have the PON peripheral (GEN3) split into PON_HLOS and PON_PBS
      (e.g. PMK8350), this can hold addresses of both PON_HLOS and PON_PBS
      peripherals.  In that case, the PON_PBS address needs to be specified to
      facilitate software debouncing on some PMIC.
