3 DA9150 consists of a group of sub-devices:
6 ------ -----------
7 da9150-gpadc : General Purpose ADC
8 da9150-charger : Battery Charger
9 da9150-fg : Battery Fuel-Gauge
14 - compatible : Should be "dlg,da9150"
15 - reg: Specifies the I2C slave address
16 - interrupts: IRQ line info for da9150 chip.
17 - interrupt-controller: da9150 has internal IRQs (own IRQ domain).
