  14   This is a part of device tree bindings for Maxim MAX77802 Power Management
  15   Integrated Circuit (PMIC).
  16
  17   The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO)
  18   regulators.
  19
  20   See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for
  21   additional information and example.
  22
  23   Certain regulators support "regulator-initial-mode" and "regulator-mode".
  24   The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h
  25   and their meaning is::
  26     1 - Normal regulator voltage output mode.
  27     3 - Low Power which reduces the quiescent current down to only 1uA
  28
  29   The standard "regulator-mode" property can only be used for regulators that
  30   support changing their mode to Low Power Mode during suspend. These
  31   regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the
  32   regulator has been enabled for the given suspend state using
  33   "regulator-on-in-suspend" and has not been disabled for that state using
  34   "regulator-off-in-suspend".
