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

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