  The valid names for regulators are:
  --PFUZE100
  sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
  --PFUZE200
  sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
  --PFUZE3000
  sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4
  --PFUZE3001
  sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4

  Each regulator is defined using the standard binding for regulators.

  fsl,pfuze-support-disable-sw:
    $ref: /schemas/types.yaml#/definitions/flag
    description: |
      Boolean, if present disable all unused switch regulators to save power
      consumption. Attention, ensure that all important regulators
      (e.g. DDR ref, DDR supply) has set the "regulator-always-on" property.
      If not present, the switched regulators are always on and can't be
      disabled. This binding is a workaround to keep backward compatibility
      with old dtb's which rely on the fact that the switched regulators are
      always on and don't mark them explicit as "regulator-always-on".

  fsl,pmic-stby-poweroff:
    $ref: /schemas/types.yaml#/definitions/flag
    description: |
      if present, configure the PMIC to shutdown all
      power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
      Use this option if the SoC should be powered off by external power management
      IC (PMIC) on PMIC_STBY_REQ signal.
      As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
