   1 AXP20x USB power supply
   2
   3 Required Properties:
   4 -compatible: One of: "x-powers,axp202-usb-power-supply"
   5                      "x-powers,axp221-usb-power-supply"
   6                      "x-powers,axp223-usb-power-supply"
   7
   8 The AXP223 PMIC shares most of its behaviour with the AXP221 but has slight
   9 variations such as the former being able to set the VBUS power supply max
  10 current to 100mA, unlike the latter.
  11
  12 This node is a subnode of the axp20x PMIC.
