  22                     <regulator_name> corresponds to a voltage switch
  23                     type regulator.

  72 The regulator node houses sub-nodes for each regulator within the device. Each
  73 sub-node is identified using the node's name, with valid values listed for each
  74 of the PMICs below.
  75
  76 pm8841:
  77         s1, s2, s3, s4, s5, s6, s7, s8
  78
  79 pm8916:
  80         s1, s2, s3, s4, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13,
  81         l14, l15, l16, l17, l18
  82
  83 pm8941:
  84         s1, s2, s3, l1, l2, l3, l4, l5, l6, l7, l8, l9, l10, l11, l12, l13, l14,
  85         l15, l16, l17, l18, l19, l20, l21, l22, l23, l24, lvs1, lvs2, lvs3,
  86         mvs1, mvs2

  88 The content of each sub-node is defined by the standard binding for regulators -
  89 see regulator.txt - with additional custom properties described below:
  90
  91 - regulator-initial-mode:
  92         Usage: optional
  93         Value type: <u32>
  94         Descrption: 1 = Set initial mode to high power mode (HPM), also referred
  95                     to as NPM.  HPM consumes more ground current than LPM, but
  96                     it can source significantly higher load current. HPM is not
  97                     available on boost type regulators. For voltage switch type
  98                     regulators, HPM implies that over current protection and
  99                     soft start are active all the time. 0 = Set initial mode to
 100                     low power mode (LPM).
