The valid names for regulators are:

--PFUZE200

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.
