* Dialog Semiconductor DA9211/DA9212/DA9213/DA9223/DA9214/DA9224/DA9215/DA9225
 Voltage Regulator

Required properties:
- compatible: "dlg,da9211" or "dlg,da9212" or "dlg,da9213" or "dlg,da9223"
  or "dlg,da9214" or "dlg,da9224" or "dlg,da9215" or "dlg,da9225"
- reg: I2C slave address, usually 0x68.
- interrupts: the interrupt outputs of the controller
- regulators: A node that houses a sub-node for each regulator within the
  device. Each sub-node is identified using the node's name, with valid
  values listed below. The content of each sub-node is defined by the
  standard binding for regulators; see regulator.txt.
  BUCKA and BUCKB.

Optional properties:
- enable-gpios: platform gpio for control of BUCKA/BUCKB.
- Any optional property defined in regulator.txt
  - regulator-initial-mode and regulator-allowed-modes may be specified using
    mode values from dt-bindings/regulator/dlg,da9211-regulator.h
