   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".
  15 - fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
  16   power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
  17   Use this option if the SoC should be powered off by external power
  18   management IC (PMIC) on PMIC_STBY_REQ signal.
  19   As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.

  21 Required child node:
  22 - regulators: This is the list of child nodes that specify the regulator
  23   initialization data for defined regulators. Please refer to below doc
  24   Documentation/devicetree/bindings/regulator/regulator.txt.
  25
  26   The valid names for regulators are:
  27   --PFUZE100
  28   sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
  29   --PFUZE200
  30   sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
  31   --PFUZE3000
  32   sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4
  33   --PFUZE3001
  34   sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4
  35
  36 Each regulator is defined using the standard binding for regulators.
