1 | Dialog Semiconductor DA9150 Combined Charger/Fuel-Gauge MFD bindings |
| 2 | ||
| 3 | DA9150 consists of a group of sub-devices: | |
| 4 | ||
| 5 | Device Description | |
| 6 | ------ ----------- | |
| 7 | da9150-gpadc : General Purpose ADC | |
| 8 | da9150-charger : Battery Charger | |
| daaab943 | 9 | da9150-fg : Battery Fuel-Gauge |

| 11 | ====== | |
| 12 | ||
| 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). | |
