   3 Required properties:
   4 - compatible: "dlg,da9211" or "dlg,da9213" or "dlg,da9215"
   5 - reg: I2C slave address, usually 0x68.
   6 - interrupts: the interrupt outputs of the controller
   7 - regulators: A node that houses a sub-node for each regulator within the
   8   device. Each sub-node is identified using the node's name, with valid
   9   values listed below. The content of each sub-node is defined by the
  10   standard binding for regulators; see regulator.txt.
  11   BUCKA and BUCKB.
  12
  13 Optional properties:
  14 - enable-gpios: platform gpio for control of BUCKA/BUCKB.
  15 - Any optional property defined in regulator.txt
