   7 Required properties:
   8 - compatible : Must be "rt,rt5025";
   9 - interrupts : This i2c device has an IRQ line connected to the main SoC
  10 - interrupt-parent : The parent interrupt controller.
  11
  12 Optional node:
  13 - Child nodes contain in the RT5025. The twl family is made of several variants
  14   that support a different number of features.
