-PFUZE100 family of regulators
-
-Required properties:
-- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
-- reg: I2C slave address
-
-Optional properties:
-- fsl,pfuze-support-disable-sw: 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: 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.
-
-Required child node:
-- regulators: This is the list of child nodes that specify the regulator
-  initialization data for defined regulators. Please refer to below doc
-  Documentation/devicetree/bindings/regulator/regulator.txt.
-
-  The valid names for regulators are:
-  --PFUZE100
-  sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
-  --PFUZE200

-  --PFUZE3000
