   1 PFUZE100 family of regulators
   2
   3 Required properties:
   4 - compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
   5 - reg: I2C slave address
   6
   7 Optional properties:
   8 - fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
   9   regulators to save power consumption. Attention, ensure that all important
  10   regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
  11   property. If not present, the switched regualtors are always on and can't be
  12   disabled. This binding is a workaround to keep backward compatibility with
  13   old dtb's which rely on the fact that the switched regulators are always on
  14   and don't mark them explicit as "regulator-always-on".

  16 Required child node:
  17 - regulators: This is the list of child nodes that specify the regulator
  18   initialization data for defined regulators. Please refer to below doc
  19   Documentation/devicetree/bindings/regulator/regulator.txt.
  20
  21   The valid names for regulators are:
  22   --PFUZE100
  23   sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
  24   --PFUZE200
  25   sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
  26   --PFUZE3000
  27   sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4

  29   sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4

  31 Each regulator is defined using the standard binding for regulators.
