  13 Required properties:
  14 - compatible : Should be "dlg,da9150"
  15 - reg: Specifies the I2C slave address
  16 - interrupt-parent: Specifies the phandle of the interrupt controller to which
  17   the IRQs from da9150 are delivered to.
  18 - interrupts: IRQ line info for da9150 chip.
  19 - interrupt-controller: da9150 has internal IRQs (own IRQ domain).
